register

norm: register

text: 1. The ribbon or cord marker attached to a book to serve as a bookmark. It is usually run under the headband (if any) and glued to the spine. Generally, the register is about 1 inch longer than the distance from the head of the book at the spine, taken diagonally to the outer corner of the tail. Registers are not used as often as in the past, possibly because of the rising cost of edition binding. They are still found fairly frequently in devotional books, especially Bibles, and cookbooks. When two registers are used, as with some cookbooks and other publications, they are called "double registers." Also called "bookmark." 2. A list of the quires or sections of a book, often printed at the end of early printed books, particularly those printed in Italy, to assist the binder in assembling and collating a complete copy in the correct order. The list may contain catchwords, signature marks, or a combination thereof. 3. In printing, a term used to indicate that the type area of the recto of the sheet coincides exactly with that of the verso; also the adjustment of color blocks so that colors are superimposed with exact accuracy. Register is of considerable importance in multi-colored printing. 4. In folding, the exact alignment of images so that the print of one leaf is exactly over that of the preceding and following leaves. 5. A book in which binding and other records are kept. 6. In paper ruling, a sheet is said to be in register when ruled on both sides the lines coincide exactly.

REGLET

norm: reglet

text:
Is a sort of furniture of an equal thickness all its length. It is quadrat high, of several thicknesses, viz. Nonpareil, Brevier, Long Primer, Pica, &c. thick.—M.

Reglet and all other furniture, except side and foot sticks, are made in lengths of three feet each, and are always styled a yard of reglet, a yard of broad, &c.; the use of reglet is to branch out titles, jobs, and other matter, to economise the use of quadrats: it is preferable to quadrats for this purpose, it keeping the lines more even; for different founts of the same size being often mixed, and the quadrats frequently battered, are not so true as a piece of reglet, which I would always have put next to a line of capitals; it is also used in making margin.

The thinnest reglet used is called card reglet, a substitute for scale-board; the regular sizes commence with Pearl and go up to Two Lines Great Primer, with the exception of Ruby, Minion, Bourgeois, Small Pica, English, Paragon, and Two Lines Pica, which are sizes not used.


REGLET

rehinged

norm: rehinged

text: A book that has had a strip of linen attached across the hinge from the flyleaf onto the board paper, so as to reinforce a torn or broken hinge. If the board paper has been lifted from the board for some other operation, e.g., the insertion of an overcast cloth joint, the new hinge can be secured to the board. In cases where the book is also to be strengthened across the joint with a new strip of leather, it is preferable to replace the hinge first, otherwise the additional thickness of the linen inside may exert pressure on the outer joint when the book is closed and create severe strain across the joint. See also: REJOINTED.


reinforced

reinforced library binding

norm: reinforced library binding

text: A type of replacement (secondary) binding in a "pre-library bound" style. The term which is now virtually obsolete, is properly used only with reference to so-called Class "A" pre-library binding; however, it is sometimes also used with reference to a pre-bound book which retains the publisher's original case.

rejointed

norm: rejointed

text: A leather binding that has had one or both joints repaired or replaced. Replacement joints are the length of the book and about 34 inch wide, the exact width being determined by the size of the book and the distance the strips are to extend underneath the spine and sides. The strips, which are pared moderately thin, have a long feathered bevel on all sides. While paring does weaken the leather, if it is too thick along the line of the joint, it will tend to lever itself off the spine each time the cover is opened.

relative humidity

norm: relative humidity

text:
See notes on the electronic edition

The ratio of the amount of water vapor in the air to the amount which would be present at the same temperature were the atmosphere to be fully saturated. Relative humidity is expressed as a percentage. Saturated water vapor pressure for various temperatures is given below:

Temperature     Saturated Vapor Pressure (mm. of mercury)

0                4.58

5                6.54

10                9.20

15                12.78

20                17.5

25                23.69

30                31.71

35                42.02

40                55.13

Thus, at 25° C., for example, if the pressure of water vapor actually present in the atmosphere is 13.77 mm of mercury, the R.H. is:

actual vapor pressure

R.H. =  ---------------------       X 100

saturated vapor pressure

or

13.77

----- X 100 or 58%

23.69

All organic fibers, including paper and leather, are hygroscopic and absorb or emit water vapor so as to adjust their moisture content to that of the air in which they are stored. Although the R.H. factor varies with different kinds of organic fiber, it remains constant for the same kind of fiber. Since the moisture content of paper affects its weight and printing properties, its R.H. must be known. It may be measured by a sword hygrometer inserted in a pile of paper.

Corresponding

Water Content of

equal Weights of

R.H. of the Air          a Cellulose Fiber

30%                     5%

40%                     6%

50%                     7%

60%                     8.5%

70%                    10%

80%                    13%

The change in rate of increase, e.g. between 50 and 60%, stems from the fact that the curve is not flat but "S" shaped; and, also, because of hysteresis, equilibrium water content is higher when approached from the wet side than from the dry side.

Any changes in water content of a fiber immediately manifests itself as changes in its dimensions, especially in the cross direction of the paper. The fiber diameter swells considerably at increased moisture content resulting in stretching of the paper. Other properties of the paper are also affected, but the most significant change affecting printing is the change in dimension. The absorption and emission of moisture require time, absorption generally requiring less than emission. The edges of paper in storage come into contact with the atmosphere to a greater extent than other areas, and are therefore exposed initially to changes in R.H. A rise in R.H. will cause the edges of the paper to buckle, while a decrease may cause undulations in the middle of the pile. In order to avoid dimensional changes in paper it is not unusual to hang it before printing. In offset printing, where attention must be given to the moisture transferred to the paper directly from the dampened plates (by way of the rubber cloth), a relative humidity of approximately 60% has been found to be suitable for purposes of register, while in other printing methods and paper handling firms, a lower moisture content may be more suitable.


remainder binding

norm: remainder binding

text: The business of binding unsold copies of a book that are in sheets or gatherings. These are sold to a jobber, bound in a different format from the original binding, and offered for sale, sometimes with a different title. Such bindings are usually very economically priced. For 19th and 20th century books, the term "remainder binding" is used correctly only with reference to a book bound for the wholesale book trade by someone other than the original publisher of the book. A later (and sometimes less expensive) publisher s binding was a SECONDARY BINDING.

remargined

norm: remargined

text: The replacement or restoration of part of one or more of the outer margins of a leaf, either by means of paper cut to size and pasted to the leaf or by LEAFCASTING. If all four margins are replaced, the leaf is said to have been INLAID.


remboîtage

norm: remboîtage

text: A French term applied to the process of transferring a book, i.e., text block and endpapers, from its original binding to another. The new binding may be more luxurious, more nearly contemporary, or simply more appropriate, than the original. The term also refers to the process of transferring a superior text of a work into a better binding than the one originally made for it. There is not a comparable English word for this expression, recasing being the closest; however, in craft bookbinding, "recasing" connotes a book that has been removed from its covers, repaired and/or resewn, and then returned to the original covers, while in library binding, it indicates a new, but usually just ordinary, case.


removable press

norm: removable press

text: A type of press that is not designed to exert pressure but simply to hold pressure that is applied. In the days when standing presses were used in edition and library binding, many presses were required because books were generally kept under pressure for 24 hours. Use of the removable press reduced the number of (hydraulic) standing presses required because it divided the application and maintenance of pressure between two implements. The books were loaded on a separate base supported on casters instead of the base of the press. When the press was filled, a special board was placed on top of the last pressing board, and, after the pressure was applied, threaded steel rods connected the top board and the caster-mounted base. The pressure of the hydraulic press was then released and the entire load of books rolled out of the press. With this equipment it was necessary to have only one press for each casing-in machine; however, sufficient special bases, top boards and pressing boards for the day's work were required.

text: A base paper used in numerous reproduction processes or systems. It may be sensitized, as in the case of negatives, blueprints, photographic paper, etc., or plain, as that used for electrostatic reproduction paper. It is usually produced from high grade bleached chemical wood pulps and/or cotton fiber pulps in basis weights ranging from 11 to 32 pounds (17 X 22—500). It is generally well sized and its more important properties include chemical purity, good wet and dry strengths, and a relatively high degree of permanence.

reset

norm: reset

text: A leaf, leaves, or an entire section of a book which has become detached and has been glued back into place. Although the technique is used by some bookbinders, it is a poor and usually ineffective method of repair.

resewing

norm: resewing

text: The process of removing a text block from its case or covers, removing the spine lining (if any), old adhesive, as well as the original sewing thread, and then resewing the sections. In conservation bookbinding, "resewing" usually implies the same method of sewing as the original; in library binding, however, the term generally implies the substitution of OVERSEWING for edition sewing.

resin

norm: resin

text:
Any of various hard, brittle, solid, or semi-solid amorphous, organic, fusible substances that are insoluble in water but soluble in organic solvents, and which are classified as natural or synthetic. Resins contain a high proportion of carbon but little oxygen, and have an indefinite and often high molecular weight. The natural resins are excretion or exudation products principally of plant origin (a notable exception being shellac), fusible, usually yellowish to dark brown in color, and transparent to translucent. "Recent resins" are those obtained from living plants, while those dug from the earth where they were deposited, are known as "fossil resins."

Chemically, resins consist of complex mixtures of organic (resin) acids and alcohols, which are generally aromatic in nature, and inert substances (known as resenes), together with extraneous fatty, mineral, or other materials. Gum resins contain carbohydrate gums, while oleoresins are mixtures of resins and volatile oils. The non-volatile residue of conifer resins is called ROSIN, which is the most important resin used in the manufacture of paper. Other more-or-less familiar resins include copal and dammar, which are natural resins used in the manufacture of varnish, accroides, amber, elemi, ester gum, manila copal, mastic, sandarac, and shellac. See also: SYNTHETIC RESINS.

resinous adhesives

norm: resinous adhesives

text:
A group of adhesives containing as their principal constituent a water emulsion of POLYVINYL ACETATE (PVA) resin. There are several formulas for PVA resinous adhesives, some of the principal ones used in conservation work being listed below:

1.  PVA                 95%

Plasticizer          5%

Water (sufficient to thin as required for best working consistency)

This composition is used both in hand binding operations and in gluing machines, and is particularly suitable in those operations involving the use of pyroxylin coated or impregnated fabrics, e.g., buckram, which are difficult to attach by means of ordinary glues.

2.  PVA                 78.0%

Dibutyl phthalate    6.3%

Gamma valerolactone  7.8%

Water                7.9%

This formula produces an adhesive which will adhere paper, leather, plain cloths, or pyroxylin coated or impregnated, starch filled, or rubberized cloths to cellulose acetate surfaces.

3.  PVA                 90%

Gamma valerolactone 10%

Water (sufficient to thin as required for best working consistency)

This is a quick drying adhesive.

4.  PVA                 32%

Isopropyl alcohol   39%

Plasticizer          4%

Water               25%

This adhesive provides excellent penetration

5.  PVA                 89%

Hexylene glycol      7%

Isopropyl alcohol    2%

Water                2%

This is an adhesive that is quick drying 217 and has excellent penetration.

resistance of leather to acid

norm: resistance of leather to acid

text: The maximum percentage of acid that a leather is capable of absorbing without deteriorating with time. Experiments involving both chrome- and vegetable-tanned calfskins indicate that rapid destruction of the chrome-tanned leather may be expected if the percentage (by weight of leather) of (sulfuric) acid exceeds 10%, while a percentage greater than 4% of the same acid will cause rapid deterioration of the vegetable-tanned skin. Most of the acid found in the chrome-tanned skin is probably in chemical combination with the chromium, whereas in the vegetable-tanned skin it exists as free acid.

retrospective binders

norm: retrospective binders

text:
Bookbinders who imitate earlier styles of binding. In the 18th and 19th centuries, many celebrated and not so celebrated bookbinders imitated earlier styles, including Padeloup and Thouvenin, who were perhaps the most famous, as well as Cape, Trautz-Bauzonnet, Lortic, Chambolle-Duru, Taffin-Lefort and Gruel among the French, and Rivieré, Zaehnsdorf, Lewis, and Clark among the English.

In the 19th century, the demand of antiquarian book collectors for retrospective bindings was so great that there was a concerted effort on the part of bookbinders to copy earlier styles. Many of these binders produced outstanding designs of earlier years, ofttimes surpassing their models in the precision and brilliance of their tooling. The vogue for such lavish bindings continued well into the 20th century.


retting

reversed v-guard

norm: reversed v-guard

text: See illustration</> A folded GUARD (1) to which a section is sewn, the folds of the guard meeting in reverse. The guard consists of several strips of paper folded with the two open ends being folded back on the guard, either together or in opposite directions; the guard may be folded over in one direction on itself and the section sewn at either end, or it may be folded over in opposite directions on itself and one or two sections sewn to it, depending on Re the thickness of the sections and amount of sewing swell required. Generally, the paper used for the guard (before folding) should be one-fourth the thickness of the section, so that when it has been folded it will be of equal thickness. The reversed V technique is used if the paper of the book is too thick to be sewn in the usual manner, and if it is not possible or desirable to hinge the leaves on linen guards, such as in an album. In addition, such a guard may be required because there is writing in the folds of the sections which would be made inaccessible by the usual manner of sewing and binding. The reversed v-guard technique places considerable strain on the sewing thread and folds of the section, particularly if the guards throw out far from the spine. Also called "meeting guard."

REVISE

norm: revise

text: An impression of each form printed on proof paper the first thing after it is laid on, and taken by the pressman to the reader or overseer, for him to examine that all the corrections in the press proof are made, previously to the impression being worked off. The compositor frequently takes the revise for waste paper; but this should never be done with that of the first form; the pressman should put it into the heap, so that it may be readily found, which keeps it damp, and the revise of the second form ought always to be pulled on it; the reader, in revising the second form, then sees the sheet perfect, which is necessary to ascertain that the matter follows, and that the furniture is right.

rexine

norm: rexine

text: A strong, coated cloth, usually in the form of an imitation leather, and used as a covering material for books. The weave and composition of the base (gray) cloth depend on the grade of cloth being manufactured at the time, and may be cotton or a cotton and rayon mixture. The cellulose nitrate coating is colored by mixing powdered pigments with synthetic oils and is applied in several layers, each being dried before the next application. Polyvinyl chloride may also be used for the coating. Embossing is done with engraved steel rollers, usually to imitate the grain pattern of a leather, but sometimes with modern geometric designs. This type of cloth has been in use since the first decades of the 20th century.

Reynes was active as a publisher and bookseller, and the bindery under his direction was the most prolific of his time. His bindings usually bear his device, initials, or, in many cases, both. Besides using panels depicting emblems of the Passion, etc., Reynes also employed a fine roll cut with his trademark—a hound, a falcon, and a bee, amid sprays of foliage and flowers. His name is also associated with the early use of gold tooling in England.

text: The so-called correct side of a sheet of paper. It is the wire (mold) side in a handmade paper, and the upper (felt) side of a machine-made paper. In both, it is the side from which the WATERMARK is read correctly. Printers often have to know which side of the paper is the "right side" because of differences in surface, as well as the undesirable effect of using sheets laid one way with those laid another way in the same publication. Flat papers are usually packed with the right side uppermost, while, if folded, the right side is outermost. In blue and azure papers, the right side is usually darker in color than the reverse side.


ring binder

norm: ring binder

text: One of the earliest forms of LOOSE-LEAF BINDING. The ring binder is a form of mechanical binding similar to the ring notebook paper binder, only much larger. This type of binder has declined in popularity in recent times because it is prone to accidental opening, and, in addition, the bulk of the spine is large in proportion to the quantity of paper it can hold. The binder is usually constructed with two or three rings mounted on a metal backpiece. A mechanism inside the metal back links the rings together so that they all open and close simultaneously, being held closed by spring tension. Some binders open when a small latch at the end of the backpiece is pressed, and close when the latch at the other end is depressed, while others have fiber strips designed to slip over the rings. When these strips are pulled in opposite directions the rings snap open. In the usual case, the bindery produces the binding, but purchases the assembled mechanism.

RISERS

norm: risers

text:
The material upon which stereotype plates are fixed, in order to be printed.

These risers are sometimes made of wood, with the plates screwed, or otherwise fastened upon them; sometimes of brass, bell metal, gun metal, or type metal; and occasionally of gypsum, or Roman cement: but, of whatever substance they may be formed, the riser and the plate together should be of the same height as types.

Mr. James Fergusson took out a patent for risers made of elastic substances, of which he published the following description, or specification:—“Now know ye, that I the said James Fergusson, in compliance with the said Proviso, do hereby declare, that the nature of my said Invention, and the manner in which the same is to be performed, are particularly described and ascertained by the following explanation thereof, that is to say: In the process of printing from Stereotype Plates, the plates are put upon, and fastened to, certain materials or apparatus, called by different names, such as blocks, matrix-plates, risers, &c., which are made either of iron, brass, type-metal, bell-metal, Roman cement, gypsum, wood of various kinds, or some other suitable substance; or, without using any such materials or apparatus, the plates are, or may be, put upon, and fastened to, the coffins or tables of such printing presses as are in general use, or upon cylindrical or any other sort of printing machines. In all cases, however, of printing from Stereotype Plates, it is necessary to apply some remedy to the unequal thickness of the plates; and the operation usually adopted is that of putting layers or pieces of paper, or other material, under the thinner places of the plates, or over the same, upon the tympan, which operation is technically termed underlaying and overlaying. Now, the nature or object of my Invention is that of saving the time and expence unavoidably sacrificed in the operation of underlaying and overlaying; and this object I accomplish by putting elastic substances under the Stereotype Plates, whereby the printed impressions from them are immediately equalized wholly or in part; for the elastic substances yield to the pressure upon the thicker parts of the plates, and at the same time afford the necessary resistance for obtaining sufficient strength of impressions from the thinner parts. It must be evident, that the elastic substances are to be interposed between the Stereotype Plates and whatever solid or firm substance may be made use of, whether blocks, matrix-plates, risers, cylinders, printing presses, printing machines, or any other apparatus whatsoever. So far as I have made experiments and trials of different elastic substances, I have hitherto found Cork to be the best calculated for the purposes of my Invention; but, in virtue of the Letters Patent granted unto me, I claim the exclusive right and privilege of applying Cork, and any other elastic substance, to all kinds of printing apparatus and machines, with the view of remedying the inequalities in the thickness of Stereotype Plates; and I also claim the sole right and privilege of manufacturing the elastic articles requisite for the attainment of this object, of vending such articles, and of granting Licenses for the use of the same. In further explanation of the manner in which my Invention is to be performed, it may be proper to state, that the Cork is prepared by cutting, sawing, rasping, and filing; and by these means it is wrought to such a uniform thickness as is required. I consider a quarter of an inch as a proper thickness, but a lesser or a greater may be adopted. If, when a determinate thickness has been fixed upon, the Cork is to be applied to some apparatus now in use, that apparatus should of course be diminished as much as is the thickness of the Cork, in order that the same height to paper may be preserved. The layers or beds of Cork may be formed either of single pieces, cut to the respective sizes of pages, or made up by several slips, whereby they may be adjusted to various widths and lengths. Whether the Cork be laid loose upon the blocks, &c., or be attached by soft pitch, shoemakers’ wax, or other adhesive substance, is unimportant; but I prefer attaching it, so as to keep it in its place. Although my Invention essentially consists in discovering the applicability of Elastic Substances for the purpose of remedying inequalities in the thickness of Stereotype Plates, yet, in this Specification, I have necessarily given my explanations by particularising Cork, that being the material which I now manufacture and prefer. How to adapt any other elastic substance, which may answer the purpose equally well as Cork, cannot be a matter of doubt or difficulty to any person practically acquainted with apparatus used in Stereotype Press-work.——In witness whereof, &c.”

Mr. T. C. Hansard took out a patent for improvements on, and additions to, Printing Presses, and various processes relative to Printing; these improvements included “Stereotype-Plate Risers, with Holdfasts or Claws,” of which Mr. Hansard published the following description:—“The Risers are made of Type Metal, or with any other metal or substance, cast in a Type-founder’s mould, having somewhat the form of what are called Quotations. I take the usual standard for Printer’s ad-measurement, and cast them quadrilateral to four Pica m’s; then longer ones as parallelograms, four by eight, four by twelve, four by sixteen, and smaller ones, four by two, four by one, and four by a half; in height they are about three-fourths of an inch, or sufficient to raise the Plate to the usual height, or somewhat higher than common Type; these being cast and dressed perfectly true, in body and height, may be easily combined to form the size of any page necessary, with the certainty of having a uniform plain surface for all the plates, however numerous; they are cast as hollow cubes, the larger combinations having divisions to give sufficient support to every square against any pressure which can be brought upon them.

“The Holdfasts or Claws are formed of Brass or other hard metal, accurately adjusted in thickness to a Brevier, or any other body chosen, with a projecting Bevil at the top. They may be of various lengths, as to 4, 8, 16, 24, or more or less, Pica m’s, the elongated parts of the larger ones being to the height of ordinary Reglet, having the Holdfast or Claw in the centre, or towards each end. They may be opened, or pierced, as well to make them lighter, as to cause them, by pressing and indenting into the furniture of the forme, to be less liable to be drawn out: the height of the Claw is about seven-eighths of an inch, or sufficient for the projecting bevil of about one-eighth of an inch to lay upon the flanch of the plate when resting on the Risers. To prepare plates for working, form with the Risers the requisite number of pages for the forme or sheet to the nearest size they may make by the various combinations, and add any difference wanting by reglet, leads, or scale-board; then lay on the Plates, and place at the head, foot, and sides of each plate as many Holdfasts as may, from the size of the plate, be deemed sufficient for proper fastening; thus for small pages, as in Octadecimos and Duodecimos, one at each side and end will be sufficient; for larger pages two or more may be thought necessary; making up the parts which they may be deficient of the length and breadth of the pages with quadrats or reglet of the same body; then proceed to make margin, or dress the formes, and lock-up in the usual mode. To change the Plates; when worked, unlock the forme, draw out the Holdfast at the head or foot of the plate, slide off the done-with plate, replace by the new one; lock up again; and if the Plates have all been cast true to one gauge in thickness, width, and length, you will have throughout the whole work exact and uniform register, and equal impression;—when the Work is completed, the same material of Risers and Holdfasts, by admitting every combination of size, will form into any other sized pages for any other sized plates.”

roll

norm: roll

text: See illustration</> 1. A finishing tool consisting of a brass wheel, the circumference of which is engraved so as to impress a continuous repeating pattern as it revolves under (considerable) pressure. The decorative roll was used in Germany at least as early as the 1460s, and was in common use by the second decade of the 16th century. Most of these early rolls were cut intaglio, so that the design on the leather was raised, but many were also cut in relief. The average length of the pattern impressed by early rolls was approximately 5 to 6 inches, which would give a wheel diameter of approximately 1.6 to 1.9 inches. The common diameter of rolls used today is about 3.5 inches, which is capable of producing an impression of about 11 inches in length. The smaller size, however, is still in use. Rolls have been produced in an enormous variety of designs, including simple lines, simple and intricate patterns, as well as edge and title rolls. 2. The design impressed by a roll. See: SCROLL (2).

ROLLER

norm: roller

text:
A cylinder coated with composition, fixed in an iron frame, and revolving upon an iron rod running through it, with which to ink the forms, preparatory to taking an impression.

The roller has almost entirely superseded the use of balls in printing; and, since the introduction of composition, I may venture to say it has completely superseded the use of pelts for balls. See Pelts.

The use of the roller is less laborious to the pressman than balls; and for common work, and indeed all work where weak ink is used, it coats the surface of the types, &c. more uniformly, perhaps, than balls; but for fine work, where strong ink must be used, and really fine work cannot be produced without strong ink, the roller is decidedly inferior to the ball, partly owing to the difficulty of taking ink and distributing it on the inking table; and partly owing to the inferiority of rolling to beating with balls, in coating the surface of the types with strong ink.

The introduction of composition in lieu of pelts has been the cause of a complete change in printing; but for this article, machine or cylindrical printing would never have been accomplished, as all the first attempts were made with skins to coat the roller, and all failed, owing to the imperfection of joining the edges; it was this that baffled Nicholson, who died before its introduction; and it was the introduction of this article that enabled König to avail himself of Nicholson’s invention and to reduce it to practice, after he had failed in his project of applying steam to the working of presses.

The composition was first introduced in printing by Mr. B. Foster, who spread it in a melted state on canvass, and then formed it into balls in the usual manner. I have been informed that Mr. Foster obtained his knowledge of its properties from a cotton manufactory, where it was used in some part of the machinery; but Mr. T. C. Hansard says that it was in the Staffordshire potteries, in which they use what are there called dabbers, that Mr. Foster first observed it.

Composition.—Mr. Hansard, a printer of extensive practice, in his Typographia, says, “The composition consists principally of glue and molasses, or treacle. I have seen various receipts of ingredients and proportions, some possessing the recommendations which distinguish the recipes of ancient physicians; namely, a vast variety of articles with counteracting properties. But the simple prescription which my experience has proved best, is, to provide glue of the finest quality, made from the cuttings of parchment or vellum; fine green molasses, pure from the sugar refiner, at least not adulterated for the bakers’ or grocers’ shops; and a small quantity of the substance called Paris-white [carbonate of barytes], and you will have every ingredient requisite for the compo. The proportions have been so variously stated, and so different from what I have found to be eligible, that I am wholly at a loss to account for such differences.

and about half a pound of the Paris-white, will make the compo of a superior quality to any other proportions, and will be sufficient for two demy rollers. The great disparity which appears in these receipts may perhaps be attributed to a difference in the quality of the materials, and to the mode of management.” Thus far Mr. Hansard on the component parts of the composition.

The late Mr. Robert Branston, an eminent engraver on wood, and who was also very skilful in printing his productions in a superior manner, told me that he made his balls of glue, treacle, and a little shoemakers wax, and that they answered as well as Foster’s. The Cave of Despair, in my Practical Hints on Decorative Printing, will serve as a specimen of his abilities in both these departments.

An ingenious printer in the country, and a good workman, sent me the following receipt, from which he used to make balls for his own use:—Take a pound and a half of glue, let it soak in cold water twelve hours, boil it without any additional water; when it is hot add half a pound of treacle, half an ounce of turpentine, and a quarter of a pound of tar; this quantity is sufficient for a pair of balls. Prepare your canvass or coarse cloth of the size the balls are wanted, by rubbing on it bees wax, (or common paste will answer the purpose after it has been allowed to dry,) to prevent the composition running through the pores; when the mixture is nearly cold, pour it on the canvass, held in a concave manner, in order that it may be the thickest in the middle, and thinner at the edges; then knock up the balls in the usual way.

Another receipt, from which a large establishment in London made their balls and rollers, and the latter both for their machines and presses, is equal parts of glue and treacle; but as the composition is affected by the state of the atmosphere, it is found by experience that in cold weather a greater proportion of treacle is required, and in warm weather a greater proportion of glue.

This establishment was of opinion that the glue known by the name of London Glue is the strongest and best.

These different receipts, each of which was held in high estimation by the party who made use of it on account of its individual superiority over others, tend to show that different proportions of the same materials with different ingredients incorporated with the mixture, produce a composition that possesses all the requisite qualities.

Casting Rollers.—Mr. Hansard gives the following directions:—“The cylinder upon which the compo is cast is made of alder-wood, turned to a requisite diameter, so that the coat of compo which it receives is half an inch. The cylinder is perforated through its centre, having a brass bush or collar driven into each end, through which is passed an iron rod, as an axis, with an enlarged head at one end, and tapped with a screw at the other.

“It is necessary to procure a mould very accurately made and well finished. Mine is made of brass, in two parts, adjusted to each other with rebates, the inside being finely turned and polished, and having flanches projecting by which the parts are screwed together by the screw and lock-burr. To each end is also fitted a collar; and a circular plate of iron is accommodated with great precision to the bore of the mould, having a projection in its centre to enter a cylinder of wood about which the compo is to attach itself, and to hold it exactly in the centre of the mould, and the other end of which is kept in a corresponding position by means of a brass piece to allow of the compo passing down between the interior surface of the mould and the wooden cylinder. There are little projections on the sides of the mould, which serve as feet to support each half in a steady position while lying upon a table or elsewhere. Previous to joining, the parts of the mould must be nicely cleaned and oiled, and the greatest care taken that no particle of compo, grit, or dirt, remain in the rebate. The parts being carefully placed on each other, and the wooden cylinder fixed inside, the screws must be put into their respective places in the flanches, and when all is properly made tight the mould is to be set upright for receiving the compo.

“The next material part of the apparatus is the melting kettle. This must be a double vessel like a glue-kettle, so that the compo in the interior may be melted by the heat of the boiling water in the exterior. For this purpose a strong boiler may be the best or readiest thing found, into which let a tin vessel be fitted, with a flanch to rest on the rim, so as to leave one or two inches clear under it. This vessel may be six or eight inches above the top of the boiler, so that the lid of the one may fit the other; and it must have a handle on each side; also a large lip for pouring out the compo.

“Being thus prepared, put the glue into a little water for a few hours to soak. Pour off all the liquid, and put the glue into the inner vessel, the boiler having in it as much water as it will contain when the inner vessel is in its place. Put it on the fire, and boil the water as quick as you please, the heat of which will soon cause the glue to dissolve, and evaporate part of the water. When the glue is all melted, add the molasses, and let them be well incorporated together for at least an hour, receiving heat from the boiling water, which is an uniform degree that cannot exceed 212° of Fahrenheit. Then with a very fine sieve, mix the white powder, frequently stirring the compo. In another hour, or less, it will be fit to pour off; and when it is, take the inner vessel out of the boiler, and pour the mixture gently into the mould through the opened brass keeper. In about an hour, if the weather be dry and favourable you may take the roller out of the mould; hang it in a cool, dry, situation, or lay it horizontally in a rack made for the purpose, and the next day it will be sufficiently hardened for use. As there will be rather more of the compo at each end of the cylinder than would work clear of the frame in which it is to revolve, cut off from each extremity about half an inch, by encircling it with a piece of fine twine.”

There is a serious practical disadvantage in the mould being formed of two pieces; that of having a seam or ridge running the whole length on both sides of the roller. This seam prevents that accurate distribution of the ink which is essentially necessary, and increases the probability and danger of producing monks in the impression, which ought to be avoided as much as possible, as destructive to good printing.

I have at different times heard complaints of the difficulty of drawing the roller out of the mould, and of the injury it frequently receives from the surface being damaged, which spoils it, and makes it necessary to be recast. This accident occasions disappointment and loss of time; as cleaning the mould from the composition which adheres to it when this happens is tedious. I attribute this to the mould being made too thin, which expands when the hot mixture is poured into it, and contracts as the mixture cools, thus becoming, by the contraction, too small for the roller, and binding it so tight as to prevent its being drawn out with facility, and without great risk of injury.

I know one house in the Metropolis that makes rollers in the most perfect manner, and experiences little or no trouble in drawing them from the mould; and I know a person who had a mould made, with the same result. These moulds were made out of a solid cylinder of metal (tin, or type metal is equally good for the purpose, and more durable), the aperture bored to the size of the required roller, and carefully polished on the inside, the tube being thick, in some instances two inches, so that it was not much affected by the heat of the composition, the expansion being very trifling, and of course the contraction small in proportion; so that the roller when cold was not compressed by the mould, or so slightly as not to cause any inconvenience or damage to it in drawing out. The inside of the mould should be carefully wiped out before using, so as to be perfectly free from dust or dirt, and slightly oiled, which causes the roller to quit it more readily.

Preservation.—Mr. Hansard says, “To keep the rollers in good condition for working, a place should be chosen where the air has free circulation, without being subject to the extreme heat of the sun in Summer, or the freezing damp air in winter; in short, in as even a temperature as possible. It will be necessary to keep a stock of more rollers than are at work; as it is frequently found, when a roller is sick, or greasy, or soft, or you do not know what is its ailment, that washing it clean, and hanging it to rest for a time, restores it to as good a state as ever.

“One other circumstance must be noticed, namely, the influence of the variable temperatures of different situations on this composition. This I have had particular opportunities of knowing, from having carried on business in two distant offices. It frequently happened that when the compo was working kindly at one office, nothing could be more teazing than its progress at the other. Indeed, while I was supplied by those who make for the trade, one of my houses frequently gave them a great deal of trouble. I have heard both Foster and Harrild say, ‘that they were obliged to make a harder compo on purpose for my house and one or two others similarly situated, than the customary temper of the mixture:’ and, frequently, the only alternative was, to find me a roller that had got hard and useless at some other house, to suit the low temperature of mine. The difference was this—one of my houses had the press-room on the ground-floor, the joists and flooring lying on the earth; the sink room adjoining; wet sheets hanging very low; very little influence from the sun, and no thorough ventilation; consequently, from the humidity of the atmosphere engendered by these circumstances, it was a constant complaint that the compo was too soft. At my other house the press-room was on the two-pair floor; the poles very high; the sun’s rays had free admittance, and the ventilation was very complete. Here the compo, complained of as too soft at the former house, was all that could be wished: hence it became the roller-nursery; and by sending them to hang up a day or two, when out of order at the other place, they became firm and fit for work.”

From this statement it appears that any fixed proportions of the materials for the composition cannot answer generally, and that they must vary according to circumstances. And it may cause us to cease wondering at the number of recipes, and of the different proportions of the various articles, and at being told that they all answered very well; for it is evidently owing to the situation, whether moist or dry, of the press-room of a printing office, that different proportions of ingredients are requisite to make a roller work well, under different circumstances.

The usual method of keeping rollers in working condition is to cover them at night, and when they are not likely to be wanted for some time, with a coating of common or refuse ink; this does not dry, and prevents evaporation, and thus keeps them in working condition: the ink must be scraped off when they are required for use. A roller will get foul in the course of working, or become too hard, it should then be washed well with lye and the lye brush, which will remove the foulness, and it may be further washed with clean water and the hand to remove the lye, and to give it a clean surface; it would then be necessary to distribute it well on a clean table. It would be now advisable to proceed with the presswork with a fresh roller, and allow the one that was washed to have a rest, which generally improves its working condition. If a roller become too hard, and the surface is clean, then washing it with clean water and the hand, distributing it on a clean table, and placing it in a damp situation, will restore it; in fact, when the press-room is dry and well ventilated, keeping the rollers in a damp situation when not in use is preferable, in my opinion, to softening them with water, as the moisture is gradually imbibed by the composition, and makes it more uniformly soft and kind.

When rollers get too soft, the general practice is to hang them up in a current of cool dry air, which evaporates the superabundant moisture, cools the composition if the room has been too warm, and brings them to a good working state. But a more expeditious and effective method, is to sponge them with spirit of turpentine, which restores them to a proper condition sooner than any other method, and also cleans them more effectually than lye. If the same rollers are required to be used when it is necessary to change the colour of the ink, there is not any article that will clean them so expeditiously, and take the ink which had been used out of them so completely, as spirit of turpentine.

Occasionally the pressman finds that he cannot produce good and clear impressions with all the care and attention that he can bestow upon his work, and this when his roller seems to be in good condition, and no apparent cause can be assigned for the deficiency of quality; the roller is then said to be sick, or tired; and the only remedy that has yet answered to remove this inconvenience is to give the roller rest; that is, to hang it up, and take another roller for the work in hand; after resting for some time, it will be found that the sick or tired roller has resumed its original qualities, and will again produce good work.

Rollers, when not in use, should always be hung up in a shady place, which is generally done by one end of the frame, for if left on the inking table they would stick to it, and the composition would be torn in the act of separation; neither should they be exposed to the action of the rays of the sun in summer, which will soften the composition so much as to cause it to run, and thus spoil the roller. These observations apply equally to composition balls.

The following is an abstract of the French method of making and treating rollers.

The French roller-makers proportions are eight pounds of glue and twelve pounds of treacle, which is sufficient for four rollers used at press; the quantity required for those used at machines will vary according to their length and diameter.

Paris made glue is the best: it ought to be transparent, have little colour, and break like glass. Flexibility in glue is a proof of its weakness; and it is injured by being left in a damp place.

The treacle ought to be pure; the most compact is the best. To avoid being deceived, it is best to buy the refined. The old is weak, and not of a good quality for rollers.

In preparing to make four rollers, two pounds of good glue must be soaked in river water; the strength of the glue must determine how long; but if too long the glue loses its strength, and the rollers are injured.

This portion of the glue, thus soaked, is then put into the melting kettle, and placed over a fire, and stirred with a spatula; and when it is quite melted, the rest of the glue is added in similar portions, till the whole eight pounds are melted, which ought to have an hour’s boiling before adding the twelve pounds of treacle. The treacle is then gently poured into the melted glue, stirring them until they are well incorporated. This done, they are left over a moderate fire for an hour, stirring them with a spatula every ten minutes. The surface must be skimmed, and afterwards the vessel must be left a little time to slightly cool, before being poured into the mould.

The cylindrical tube in which the rollers are cast should be smeared in the inside with a brush with oil; neatsfoot oil is the best; and it is necessary that every part should be carefully oiled, and that the wooden cylinder should be well cleaned and free from moisture.

These observations can only apply generally to the making of rollers; it is practice which can alone furnish the particulars. The temperature varying in each season must be the object of special attention, as it renders the materials more or less flexible, and requires the composition to be more or less boiled.

It is a fault with rollers when they lug too much, as it detaches the composition from the wooden cylinder. When they are moist they should not be too much washed, as that also tends to make them lug, and detaches the composition. If they are used too soon after making, they distribute the ink badly, fill up the letters, and last but a very little time. They ought to be exposed to a current of air to dry them, and to be carefully scraped before being used, and again afterwards. If they are too dry they must be sponged all over and distributed upon the table until the water has disappeared, and then on a clean table, before taking ink. When they begin to grow old and hard by work, they must be washed in proper lye without being rinsed in water, and care and attention given to their wiping; and by these means they may be preserved for a considerable time. Rollers, when not in use, should be suspended in a place neither too dry nor too damp.

Recasting.—Before recasting old rollers, take great care to wash them well with lye, in order to detach the ink with which they are coated: if they are dry they must be scraped with a knife, as grease deteriorates the matter. Afterwards cut the composition all over with a knife, and it will then be easily detached from the wood. If it is new it will not need cutting, it will easily dissolve; if old it must be cut into little pieces, that it may dissolve more easily, and with less loss: if the composition is very strong, the little pieces must be washed in a pail of water, warm water is better than cold; add to it two pounds of treacle, for four rollers, and so in proportion: when the matter draws out well in threads, the composition is good.

If the rollers have been recast many times, and they draw too much, they may be recast without adding fresh treacle or glue. Rollers which are recast are better than new; they are more elastic and less melting. With three pounds of glue, five pounds of treacle, and the matter of three old rollers, four rollers can be made; if a small glass of spirits of wine be added it will facilitate the dissolving.

The rollers fail the most frequently at the ends. They ought to be dry, and clear from grease. It is a good plan before using them to scrape them clean, and to sponge the ends for about an inch and a half with spirits of wine, and to leave them to dry; the gelatine draws better.

roller backer

norm: roller backer

text: A bookbinding machine, invented by the American, Charles Starr and exhibited by him in 1851 at the London exposition. It is used to create the backing shoulders of a text block which has previously been rounded, usually by hand. It consists of a heavy roller pivoted above a pair of jaws. The book is clamped with that part of the text block equal to the extent of the backing shoulders projecting above the jaws. The roller is adjusted so that it swings back and forth across the jaws in an arc that corresponds to the round of the spine. The roller is then lowered so that it presses on the spine and is rocked back and forth to shape the spine into the proper shape, bending the sections over the jaws and thus creating the shoulders. If too great a pressure is applied directly to the spine, the sections may be buckled and creased on the binding edge; in addition, the endpapers and several leaves of the first and last sections may be cut by the edges of the jaws. See also: BACKING; ROUNDING AND BACKING MACHINE.

rolling

norm: rolling

variant: rolling machine

text: The process of smoothing and compressing the grain surface of leather by subjecting it to the action of a metal roller under pressure. Unlike GLAZING, rolling involves the use of a revolving steel roll and is usually done in a rolling machine, or rolling jack, which is very much like the glazing machine, except that the latter has a stationary roll made of solid glass in place of the revolving steel roll. While the steel roll strikes the leather with considerable pressure, there is no great friction, as in glazing, and no measurable heat is generated. While being rolled, the leather is usually rotated so that the entire area is rolled twice, a process referred to as "rolling twice around."

rolling machine

norm: rolling machine

text: A bookbinding machine at one time used to flatten and consolidate the sections of a book before sewing. It consists essentially of two iron cylinders, each of which is about a foot in diameter. The distance between the rolls can be adjusted by means of a screw. The sections are gathered into packets of anywhere from two to four and placed between tin plates. The number to be rolled at a time depends on the thickness of the sections. The "book" of sections is then passed between the rollers and removed by the workman turning the crank. Before the invention of the rolling machine (in 1827), which was the first machine to be used in the craft of bookbinding, sections were compressed by pounding them with heavy beating hammers. Not all books were suitable for rolling, e.g., old books with a heavy type impression and deep corrugations across the type area; therefore the hammer continued to be used during the remainder of the 19th century, although its use diminished steadily. The modern counterpart of the rolling machine is the BUNDLING PRESS.

Roman numerals

norm: roman numerals

text:
The capital letters used as numbers in books, for chapter headings and the designation of part numbers, appendices, on title pages for dates of publication, etc. They are also used in lower case for the pagination of preliminary pages. The Roman capitals most commonly used as numerals are:

I        1

X       10

L       50

C      100

D      500

.

Combinations of numbers are made by the addition and subtraction, e.g., XX = 20, XIX = 19, XXI = 21, MCMLXXVI = 1976, etc. 1,000 was at first represented by the Greek letter phi &phgr;, which in lettering and architectural inscriptions became CI, which then became M. 500 was half a phi, or I&revc;, which later became D. 100 was represented by the symbol for theta &thgr;, which later became T, then C, while 50 was represented by the Chaleidian form of the letter chi</> XXX, which became XXX and later L. Below are listed most of the known numerals:

B                         300

Romanesque bindings

norm: romanesque bindings

text: A group of bookbindings dating from the 12th and early 13th centuries. These bindings, of which more than a hundred examples are recorded, are always in leather, usually of a dark brown color. Their decorative patterns were not incised with a knife or graver, as was common in that time, but were produced by means of repeated impressions made with engraved metal stamps. The finest examples are of French or English origin, but the style was also prevalent in Germany, although not in Italy or Spain. Romanesque bindings are the earliest of the blocked bindings and represent a fully developed art of book decoration by means of deeply engraved metal dies, which left excellent impressions in relief in the leather. These 12th century stamps are well engraved, and seem to have no known antecedents. There is evidence indicating that they were produced by the members of a small group of monasteries, and within a relatively short period of time. Most of the extant examples are bindings of individual books of the Bible, each usually having a different design on the upper cover.

ROSE ENGINE

norm: rose engine

text:
The rose engine is, I believe, a French invention, and has long been used for turning ornaments on metal, for instance, watch cases and other articles of plate; it was afterwards applied to produce them to print from by the rolling press: during the sitting of the commission for inquiring into the best means for preventing the forgery of bank notes, about twenty years ago, Mr. Perkins introduced a specimen bank note which was partly executed by this machine; and the late Mr. Branston, then of the firm of Whiting and Branston, was, if I am not mistaken, the first to engrave by its means for letterpress printing, and the tickets and shares for the last state lottery were executed by it at Beaufort House. Its great value for the prevention of forgery is, that all circles, curved and angular lines produced by this machine are precisely similar to each other and true, however numerous, and however small or large; it would be next to impossible to produce the same designs, with the same accuracy, by the hand, and the operation would also be uncommonly tedious.

By the kindness of Mr. Holtzapffel I am enabled to introduce into this work a number of different patterns; only one specimen of each individual apparatus is given. The patterns which are capable of being produced are almost endless, and depend on the skill and taste of the operator; the variations in the designs being caused by different chucks being used in the operation; and the combinations of the effect produced by each chuck, either in straight lines, circles, ellipses, or as a ground covering the whole surface, in many instances are very delicate and have a beautiful effect. The following enumeration shows how the annexed specimens were produced.

Figs. 1. 10. Holtzapffel and Co.’s compound oval and eccentric chuck:—1. Two eccentric movements; 10. One oval and one eccentric movement. 2. 6. 8.

By John Holt Ibbetson, Esq.” Third Edition, 8vo. London. [1840.]

Mr. Ibbetson observes, “The number of beautiful designs which may be obtained by combining, on this principle, two circular adjusting movements is inconceivable. Consecutive circles, &c. may be arranged, not only in elliptical curves, but in the shape of hearts—in straight lines—in triangles—in squares—in polygons, and in both inward and outward looped figures.”

rosin size

norm: rosin size

text: A solution or dispersion obtained by treating ROSIN with a suitable alkali. The resulting size may be fully saponified or it may contain free rosin acids. When properly converted in the papermaking process, usually by the addition of ALUM, the size precipitates and imparts water (ink) resistance to paper. Since in its natural state rosin is insoluble in water; it must be altered chemically before it can be used as a sizing material. Although several methods of treatment exist, the one in general use today is basically the same as that used in the manufacture of soap, i.e., saponification of a portion or all of the rosin with caustic soda or soda ash to form a soluble rosin soap. Unreacted rosin, which is held as an emulsion, is known as free rosin. The percentage of free rosin has been found to affect the sizing efficiency of a material to a certain degree, the extent depending on variations in conditions in local paper mills.
