slipsheet

norm: slipsheet

variant: interleaf

text: The paper or other material inserted between printed sheets in order to avoid offsetting an image on one sheet onto the back of the next sheet. In terms of the preparation of copy, "slipsheet" means to insert pages into proper sequence to indicate the placement of illustrations that have not yet been prepared. Each page. or slipsheet, identifies its particular illustration, along with information as to whether the illustration is line or halftone, foldout or horizontal, as well as the size, the negative or art file number, the figure number and titles, and any other information that might serve to key illustration to its proper page for printing or collating.

SLUR

norm: slur

text:
—When from any cause at press, the impression on the paper is smeared, it is said to Slur.

This may arise from many causes—if the tympan joints are loose, it will be produced by the least lateral movement of the tympan after it is turned down—if the ear of the frisket touches the inside of the cheek in running in, it will cause it—if the press runs close, so that the inner tympan touches the face of the platen, it is very likely to slur; and I have often observed this in wooden presses that had been altered to obtain the additional power, for the platen was brought so low and near to the face of the letter in the form, as not to allow room to run in clear. In presses where the tympans are large, if the slur pin does not act, that corner of the tympan will come in contact with the form first, and cause a slur, particularly if the tympans are in any way rickety, or twisted by drawing on the parchment. Where the winter has been justified with cards, to produce a greater spring in the pull, it has been known to produce slurring. The first step towards curing this defect is to ascertain from what cause it arises; and then it is not difficult: but it has often caused great trouble to discover the cause.

The following are my old Pressman’s directions “To prevent Slurring and Maculing;” and though it will be perceived that some of them apply only to wooden presses, yet the whole may be useful.

“1. Keep the face of the inner tympan and platen clean and dry.

“2. Be sure that the parchments are tight both on the inner and outer tympans; also that the tympans are not rickety, nor the joints slack.

“3. Guide cramps are a great preventive to slurring and maculing.

“4. The tenons in the head and winter must exactly fit the mortises in the cheeks.

“5. The short bolts must be screwed tightly up, to fix the nut or box firmly in the head, and must not have the least play.

“6. The garter must fit the spindle and hose, and the spindle must fit the hose, as exactly as possible.

“7. The hose must work perpendicularly, and steady in the shelves.

“8. The platen must be tightly and properly tied, or otherwise fixed, so that it shall come down upon the face of all the types in the form at the same moment.

“9. The wheel must be well justified on the spit.

“10. The railing of the inner tympan must not rub against the platen, in running in or out.

“11. The shanks of the points must not be so far over the outer part of the tympan as to rub against the cheeks of the press.

“12. If a clumsy smith has made the joints of the frisket so thick as to cause the tympan to rub against the face of the platen, he must alter them at his own expense.

“13. The shelves must be quite steady.

“14. The press stone must be worked down with hard pulling until it becomes a fixture.

“15. The frisket must be quite even, and fall flat on the form; and the paper which is pasted on it must not bag.

“16. Fix the winter as solid as possible.

“17. Let the tympans fall easily on the form, neither driving them from you, nor pulling them to you in letting them down; neither let the platen touch them till they are quite run in, nor run them out till the platen is quite clear of them.

“Exclusively of the aforesaid, there may be many other causes of slurring, which the pressman can only discover by close attention. I have often found cork bearers a great preventive.

“I have heard many complaints of the middle pages of a twelves form maculing at a two-pull press; but this is not always the fault of the press. The cause frequently is owing to blankets being in the tympan which have been used for folios, quartos, octavos, &c. &c.; and instead of its being a macule, it is nothing more than that part of the blanket which had covered the short cross of other work, and in the twelves form caused a deep and ugly impression, looking like a macule: this evil can only be remedied by new blankets, or confining the use of them to 12mo. forms.”

SLUR

text: A blurred impression in a printed sheet.


SLUR PIN

norm: slur pin

text: —A flat-headed screw, that goes through the off side of the outer tympan, near the head band, so as to rest on the chase or furniture. Its use is to prevent the off corner of the tympan from coming down on the types before the other parts, which when it happens causes slurring.


SMALL CAPITALS

norm: small capitals

text:
—Capitals of a smaller size than the regular capitals of a fount, but cast on the same body; thus the small capitals of Double Pica are about the same height as English capitals. They bear off more from each other, and are stouter, in proportion to their size, than the capitals of the same fount. They are used for running titles; for heads of chapters; for emphatic words; and for subordinate lines in titles and jobs. Till of late years small capitals were only cast in England to founts of Roman letter; the type founders cast them now occasionally to Italic letter, and they form a useful sort.

Moxon does not mention small capitals; nor are they in the plan of the cases of Roman letter which he gives in his work. See Sorts.

variant: small paper edition

text: A copy, or edition of a book printed on paper of a smaller size than that of a LARGE PAPER COPY. The paper, however, is usually the normal size for the edition and therefore perhaps should be called "plain paper copy," or not be given a designation at all.


SMALL PICA

norm: small pica

text:
—The name of a type, one size larger than Long Primer and one smaller than Pica. It is half the body of Double Pica in depth. Moxon does not enumerate it in his Table of the sizes of each body; but, after giving the names of the different types, he says, “These are the bodies most of use in England; but the Dutch have several other bodies: which because there is little and almost no perceivable difference from some of these mentioned, I think they are not worth naming. Yet we have one body more which is sometimes used in England; that is a Small Pica, but I account it no great discretion in a master printer to provide it: because it differs so little from the Pica, that unless the workmen be carefuller than they sometimes are, it may be mingled with the Pica, and so the beauty of both founts may be spoiled.” See Types.

This was published in 1683, and opinion has changed so much respecting this size, that at the present day there are perhaps more works printed with it than with any other size.


smalt

norm: smalt

text: A potassium cobalt silicate glass of a deep blue color. It is pulverized under water for use as a coloring material in papermaking. It consists of 50 to 70% silica, 12 to 22% potassium oxide, and 6 to 16% cobalt oxide, and is prepared by fuzing crude cobalt oxide (called "zaffre") with silica and potassium carbonate. It must be pure; otherwise its color is adversely affected. It is usually used as a loading agent, and because of its resistance to acids, alkalis, heat, and moisture, its fastness is excellent; however, because of its relatively low coloring power it is expensive to use, and is, therefore, used mainly for the more costly handmade and better machine-made azures used for writing papers. Its high specific gravity usually causes it to sink through the pulp and color one side (the wire side) more than the other. At one time the term "smalt" was used to describe the vitrified pigment used for painting on glass and was not necessarily limited to blue.

text: The operation of reducing the bulk of the entire text block, as opposed to NIPPING (1). Smashing compacts and consolidates the text block. driving the air from between the leaves. Smashing is particularly important in edition binding because it is essential that the books be of uniform thickness so that the machines, e.g., rounding and backing, casing-in, etc., can be set up just once for the entire run of the edition.

smashing machine

norm: smashing machine

text: A vertical press that is used to apply enormous pressure to material. Smashers are often provided with automatic conveyer belts, the books being piled at one end of the press on the belt in equal numbers in several piles and automatically conveyed under the smasher head. There the books are smashed either once or twice, as required, and then moved out of the press by the same conveyer, from which they are removed manually. The smasher remains for a preset time in its compressed position (DWELL TIME). It has no clamp to prevent the slippage of sections and can therefore be used to smash only those books that have so little swell in the spine that they will not RUN IN, otherwise they must first be nipped. See: NIPPING PRESS. At times it is possible to smash books with considerable swell by feeding them in pairs of two with the spines alternating and the fore edges projecting beyond the spines. See also: BUNDLING PRESS.


Smith, Charles Philip

text:
An English bookbinder and painter who received his education at Ackworth School and his art training at the Southport College of Art. He also studied under Roger Powell at the Royal College of Art, and was awarded a 1st Class diploma in 1954. Smith worked with Sydney Morris Cockerell from 1957 to 1960, and since then has worked as a free-lance creative bookbinder and painter. His bookbindings have been exhibited widely both in Great Britain and abroad, and are to be found in the collections of the British Museum, the Victoria & Albert Museum, the New York Public Library Spencer Collection, and other libraries and museums, as well as numerous private collections.

Smith has been responsible for many innovations in construction and covering technique, design, and the use of materials. He created the BOOK WALL, as well as several new techniques in cover treatment, including the feathered ONLAY, and re-constituted and sectioned onlays, which allow a greater variety, subtlety, and fluidity of color and surface, all essential to his particular mode of expression. Smith is a member of the Crafts Centre of Great Britain (1956), the Guild of Contemporary Bookbinders (1959), and the Society of Artists and Designers (1967). He is also the author of The Lord of the rings and other bookbindings (1970), and New directions in bookbinding (1974).


smoke tanning

norm: smoke tanning

text: A method of tannage used in combination with an oil tannage, whereby the fat-saturated skins are subjected to the smoke of wood fires. The smoke from the charring wood contains aldehydes, acetaldehyde, and formaldehyde, which have tanning properties. The heat also assists in the oxidation of the oil, promoting further aldehyde and polymer production. Some volatile tarry substances also often become included in the skin. Smoke tanning, simply because it involves aldehyde formation from the partial oxidation of woody materials, can be used to tan hides and skins without the need to use fats. Although a minor tannage method, it is still being used in North and South America, as well as in China.

Smyth, David McConnell

norm: smyth, david mcconnell

text:
An Irish-American, who was for the most part self taught. and who become a prolific inventor and one of the foremost pioneers in the design of bookbinding equipment. One of his first machines was an "all along" sewing machine which he patented in 1868. This machine used straight needles, the number depending on the long dimension of the book (but always one more than the number of tapes used). The notched (sawn) sections, open and flat, were fed by hand above the needles and positioned so that the needles protruded through the saw cuts. A spring-loaded. hand-operated rod passed thread to the hooked needles and retracted. The operator had to refold the section. closing it over the stitch before feeding another.

Smyth also patented a multiple-stitch, off-and-on book sewing machine in 1879. the same year the Smyth Manufacturing Company was organized. Since that time, the Smyth Company has developed more than fifteen versions of the Smyth sewing machine, including a machine that will simultaneously sew "two-up," i.e., two separate, but not yet cut apart, books (imposed for printing "two-up.") This model can take sections from 3 to 10 1/2 inches in width, up to 7 1/2 to 19 inches in height at a speed up to 85 sections a minute. The company has also designed and produced a number of other bookbinding machines, including case-making, gluing and pasting, book trimming, casing-in machines, etc.

David Smyth's contribution to book sewing was such that his name is virtually synonymous in the United States with machine book sewing. See a1so: MACHINE SEWING.

Smyth-Cleat sewing

norm: smyth-cleat sewing

text: See illustration</> A method of machine sewing or lacing adapted from an earlier European method by the Smyth Manufacturing Co. in the late 1960s and early 1970s. It combines thread and adhesive to secure the leaves of a book. In a separate machine, the back of the sections are planed off leaving the spine as smooth as possible. This is a very critical part of the operation, because if the cut spine is not smooth and even, subsequent operations are affected detrimentally. The block of leaves is then placed spine down in the Smyth-Cleat machine and is moved into position where a circular saw cuts a number of cleats completely across the back from head to tail (the number depending on the long dimension of the book). The sawn leaves then move into the sewing position where a single hollow needle laces thread around the cleats in the manner of a fiddle or figure-eight stitch. The sewn text block is then ready rate of setting; however, if the book is to be rounded and backed, an adhesive other than a hot-melt is required. because of the DRYING MEMORY of hot-melt adhesives.

soaking

norm: soaking

text:
1. The process of treating raw hides and skins with water. The restoration of moisture lost during curing and storage, as well as the removal of extraneous matter are of prime importance in converting raw stock into leather. The restoration of moisture is essential because: 1) the stock may otherwise be physically damaged by the action of washing under agitation, and flexing during green or lime fleshing; 2) sufficient moisture within the stock is necessary for solution and elimination of salts and globular proteins contained within the fibrous hide structure: and 3) the replenished water serves as a diluent as well as a vehicle for penetration into the fibrous structure of the astringent chemicals employed to effect hair loosening, plumping. and required alkaline action. Removal of extraneous organic and inorganic matter, except epidermis and flesh, by soak-washing is essential because: 1) solid matter in excessive amounts can result in both stock and machine damage during fleshing a nd unhairing; 2) manure and urine are ideal foods for bacterial growth during soaking. (Such matter, along with certain salts in the soaks, can result in discoloration and stains on the stock that cannot subsequently be removed): 3) the cementing effect of globular proteins upon dried tanned fibers reduces fiber mobility necessary for softness and good handle in the final leather; 4) curing salts transferred to the lime liquors affect the alkaline plumping action, reduce the rate of unhairing, and cause a contraction of the grain surface of the stock; and 5) the presence of extraneous matter presents a false and variable hide substance weight in determining the amounts of materials required for liming.

Because of many variable conditions. the time and temperature of soaking varies considerably according to the kind of stock being treated. Generally, few soaking aids are used in soaking cured and brined stock unless a considerable number of a given lot have been stored under exceptionally dry and warm conditions. In such cases. either sodium sulfide (63%) or sodium hydroxide may be used to the extent of 1.0 to 0.S pound respectively per 100 gallons of water. These chemicals are frequently employed in the soaking of dry stock. Excessive amounts will cause a high grain in the leather.

2. The process of wetting the grain side of a leather with water and the flesh side with paste to improve the pliability of the leather preparatory to covering.

sodium sulfide

norm: sodium sulfide

text: A reddish-yellow compound (NaS), generally prepared by the reduction of sodium sulfate with carbon monoxide or hydrogen. It is soluble in water and is used as a sharpening agent in lime liquors. It forms both sodium hydrosulfide and sodium hydroxide when dissolved in water. Its action is much more caustic than that of SODIUM HYDROSULFIDE.

SOFT INK

norm: soft ink

text:
Ink or varnish moderately boiled.—M. It is now generally termed Weak Ink.

The varnish of soft or weak ink is not so strong as that for fine ink; it does not require so much time and labour to distribute it on the balls and rollers, and it more readily covers the face of the type: on these accounts, as well as the expense, it is used for common work, as it enables the pressman to make more riddance; it is also used for machine printing, as the rollers passing rapidly over the forms with their own weight only, are found not competent to coat the face of the type with strong ink.

Solander box

norm: solander box

variant: Solander book-box portfolio

text:
See illustration Part 1</> See illustration Part 2</> A more or less elaborate book or document box invented by Dr. Daniel Charles Solander, a botanist, during his tenure at the British Museum (1773-1782). The Solander box, which is generally of a drop-back construction. is made of wood, has dovetailed joints and a back shaped from a single piece of wood. The top and bottom are held in place by screws and glue. The box is secured by two spring catches fixed in the "fore edge" frames near the head and tail. When properly constructed the Solander box is very nearly dustproof and almost waterproof. The box. which can be made as elaborate as the maker desires, is generally covered in cloth, or, in more elaborate instances, full morocco. It may even have raised bands on the back (corresponding to the spine of a book) and may he tooled.

The drop-back Solander is intended to house a book. For document storage, specifically to facilitate removal from the box, a drop-front box may actually be preferable, although in a strict sense it may be argued that such an arrangement is not really a Solander box. Aside from this, however, the drop-back box has a distinct advantage over the drop-front type in that the former imposes virtually no strain on the hinge of the box because it is in a right-angle position when closed and assumes a straight line position when opened. The drop-front box. on the other hand, with its fixed back, strains the hinge at the hack because of the approximate 60' angle at the top when the box is open. If the top is accidently struck when the box is open the top may break off.

Spanish marble

norm: spanish marble

text:
A marble pattern of soft colors, including pale green, old rose and brown (or fawn), with a MOIRÉ EFFECT. It was used in Spain from the early 17th century and is found on the more familiar later Spanish marble papers that have been used in both England and the United States since the end of the 18th century.

The best size for executing the Spanish pattern is said to consist of a combination of gum tragacanth and flea seed.

In mixing the colors for this pattern, each successive color requires more ox gall than the preceding one. The main, or body, color must also be thicker and mixed with more gall than any of the other colors.

The wavy effect of the early Spanish marbles was not nearly as even as in the later examples, and was almost invariably executed on a relatively heavy laid paper. The distinguishing moiré or watered effect, which sets the Spanish marble apart from all other types, is produced by a series of lines, shading from dark to light, crossing the entire sheet in a diagonal direction, and is the result of the method by which the paper is laid on the size after the colors have been dropped on. The sheet is held at two diagonally opposite corners and is kept in as upright a position as possible. With the sheet inclined toward the left, the corner held by the right hand is lowered until it barely touches the floating color. As soon as the paper starts to fall on the surface, it is slightly agitated with a regular motion, while at the same time being gradually lowered with the left hand until the entire sheet is on the size. If properly done, shaded stripes will appear on the paper when it is removed from t he size. These strips vary in width, depending on how much the paper was agitated while it was being lowered.

spatter papers

norm: spatter papers

text:
Another form of PASTE PAPERS. A very thin mixture of colored paste is applied to the paper by rubbing a stiff paste-charged brush across a hair sieve, which is held well above the paper and moved across the surface of the sheet as the fine specks of color are sprayed through it. Three or four colors are generally used in making these papers, which are often executed on a colored paper background.

This simple form of decoration was used for the sides of half bindings in calfskin and sheepskin in the early 19th century. They were produced all over Europe until about 1850, and were used as endpapers in books with marbled-paper covers but seldom for bindings in full leather.

A variation of this paper, used in France, England and the United States in the latter part of the 19th century, consisted of dull gray-blue or lavender-purple paper spattered with coarse black spots. This was done by striking a brush filled with color on a bar and distributing the color as it fell over the surface of the paper. These papers were used as covers for inexpensive books but seldom for endpapers. The earlier examples had a dull finish, but others, used mainly for music scores, had a glossy surface. This type of spatter paper was sometimes hung up before it was dry, the surplus color running down across the paper in uneven streaks. This dribbled pattern is almost always found in tones of brown or orange and black, and is considered by many to be less appealing than the simpler spatter papers.

spine lining

norm: spine lining

text:
1. The process of reinforcing the spine of a sewn book, after gluing-up, rounding and backing, and before covering or casing-in. The spine lining material (which is usually a fabric) does not generally extend closer than within 1/8 inch of the head and tail of the text block. In edition and library binding, the lining material, or initial liner, if there is more than one, extends beyond the edges of the spine, and is attached to the boards of the case; any subsequent lining, however, stops at the shoulders of the spine.

The purpose of lining the spine is to support it and to impart a certain degree of rigidity, while still maintaining the necessary flexibility for proper opening; consequently the weight and stiffness of the spine lining material is of considerable importance. See also: SPINE LINING FABRIC; SPINE LINING PAPER. 2. A term used incorrectly with reference to the strengthening or stiffening of the area between the boards of the covering material of case bindings. This lining is more appropriately called the INLAY (1).

spiral binding

norm: spiral binding

text: A form of MECHANICAL BINDING used for art reproductions, commercial catalogs, instruction books, books in single sheets, etc. The leaves are drilled or punched near the binding edge to take a spiral-twisted wire or plastic coil which is drawn through the holes. A tendency for the coil to be torn through the holes makes this type of mechanical binding unsuitable for publications likely to be subject to much use or careless handling. The binding margins of such publications are frequently less than 1/2 inch, and part of that is taken by the holes, which makes rebinding difficult if the publication must be sewn, as the holes can cause breakage of the needles and punches of an oversewing machine. Furthermore, in many cases, the type of paper used for these publications does not lend itself well to adhesive binding. Also called "coil binding," or "spirex binding."

If the name of the animal from which the split originates, or the word "hide" or "skin," or the part of the animal from which it is taken, is included in the description, then the word "split" must be used as a noun, e.g., pig split, hide split, butt split, and not as an adjective, e.g., split pigskin. Cf: SPLIT HIDE.

split back-gauge

norm: split back-gauge

text:
A type of movable BACK GAUGE of a paper cutting machine made up of two or more sections. Split back-gauge machines are designed especially for trimming books and pamphlets (in edition and pamphlet binding), and are unlike machines designed for cutting piles of paper, which have solid back gauges. Each of the sections of the split gauge may be set at a different distance from the knife, so that the trimming gauge for two or three different margins of a book may be set simultaneously. This permits trimming a book or a pile of books or pamphlets without changing gauges or waiting for entire lots to go through the trimming of one edge. If the split gauge is in three sections, the middle section is generally set for trimming the fore edge, and the left and right hand sections for trimming the tail and head edges, respectively.

The split gauge trimmer was used extensively in edition binding until largely superseded by the THREE-KNIFE TRIMMER. When both types are used in one bindery, the three-knife machine is generally used for pamphlets (periodical issues) and the split gauge machine for books.

split boards

norm: split boards

text:
See illustration</> The boards of a book that are made up of two or more plies of board glued together, except for a distance at the inner edge into which the slips or tapes are glued when the boards are being attached. Generally, if two boards are used they are of different thicknesses, with the thinner of the two adjacent to the text block. If three boards are used, the thinnest is placed in the center and does not extend all the way to the inner edge, thus providing the space for the tapes or slips. In the past some "split boards" were made by splitting a single ply board, either by hand or by machine, thus eliminating the cost of laminating.

The split stopped an inch or so short of the head and tail of the board (in case binding), which made it possible to make the case separately and then attach it to the text block by gluing the tapes into the splits of each board.

Split boards are used today almost exclusively in hand binding and then only for books sewn on tapes, although the technique has also been used occasionally for books sewn on recessed cords.

splitting

norm: splitting

text:
1. The process of dividing a hide or skin horizontally into two or more layers. Before the introduction of splitting machines, a hide was reduced in thickness by SHAVING (2) after tanning. The modern splitting machine has a flexible knife in the form of an endless band moving at high speed over a pair of large pulleys. When the leather to be split is placed on the bed of the machine and pushed forward, it is gripped by pairs of rollers and propelled forward in such a manner that the band knife cuts it into two layers. The propelling rollers are made up of a large number of small ring rolls with rubber centers which allow for initial variations in the thickness of the hide. The knife can be adjusted to slice through the thickness of the hide at any desired depth below the grain surface by adjusting the level of the rollers. While the machine is in operation, the band knife is automatically sharpened by grinders on its underside.

Splitting may be done while the hide is in the limed or partially limed condition, or following tannage. Hides are sometimes split in the limed condition so that a grain layer of desired thickness may be taken off and tanned separately from the splits. A gain in yield of the resultant grain leathers may be expected as a result of the slight "letting-out" of the fiber structure consequent to splitting before tannage. In certain tannages, such as vegetable tannage of leather for purposes not requiring the full thickness of the hide, savings in materials and shortening of processing time may also be effected.

When the hides are to be split in the unhaired or limed condition, the stock is plumped to a condition of sufficient firmness or solidity so as to be fed through the splitting machine smoothly in order to split off the grain layer of desired thickness uniformly across the full width and length of the hide. The fibers have a more vertical position when the hide has been plumped and will stand up against the beveled cutting edge of the band knife with less tendency to leave gouges or uneven ridges and valleys.

Although it may be highly desirable (or necessary) to reduce the substance of a hide or skin by splitting, the operation may also have undesirable effects. The strength of leather is not uniform throughout its thickness, and the grain layer, which contains the thermostat mechanism of the living skin, is relatively weak. As nearly all of the strength of leather lies in the corium, the strength of a grain split will depend upon the thickness of the corium layer which it contains. Splitting always causes a loss of strength per unit width and the sum of the strengths of the splits is always less than the strength of the unsplit leather. In fact, the breaking strength of the grain split of a vegetable-tanned calfskin, for example, will be between 3.5 and 12% of the unsplit skin, while the breaking strength of the flesh split will be between 54 and 70% of the unsplit skin; thus the leather loses between 18 and 42.5% of its strength because of splitting.

spokeshave

norm: spokeshave

text: See illustration</> A wheelwright's drawing knife used for shaping and finishing spokes, and used by bookbinders for paring leather and beveling boards. It has an adjustable blade which may be flat or curved. The tool is modified for paring by widening the gap between the blade and the guard to prevent clogging. In addition to this, the bottom of the blade is generally ground at a shallower angle, because a steep angle would result in too much of a scraping action. Because it is safer (in that there is little or no possibility of cutting completely through the leather), as well as faster, the spokeshave has largely replaced the paring knife.

SPOTTISWOODE PRESS

norm: spottiswoode press

text:
This is a beautiful contrivance, and was, as I understand, the invention of Andrew Spottiswoode, Esq., who has several of them in action in his extensive establishment. It is moved by steam, and prints two forms at the same time, which pass alternately under the platen, producing at its average rate of working seven hundred impressions of each form in the hour.

The frisket is attached to the tympan at the bottom near the tympan joints, so that when the tympan is lifted from the form by the machinery they open at the upper end, contrary to the usual way in presses worked by manual labour, and the printed sheet is left by the tympan resting on the frisket, where the paper was previously laid on.

I believe this is the first successful application of steam, as a motive power, to printing presses with a platen and a perpendicular pressure. I heard the late Alexander Tilloch, Esq., say that he intended to apply it to the presses with which the Star newspaper was printed, but he never carried it into effect; and Mr. Koenig came to England solely for this purpose; but after some years passed in making experiments, assisted by English capital, he was completely foiled in the attempt, and afterwards worked upon Mr. Nicholson’s plan, and produced a machine to print with cylinders.—See Machine.

SPRING OF A FORM

norm: spring of a form

text:
When a form has a great quantity of furniture in it, and is locked up very tight, it frequently springs up in the middle, so as to endanger its bursting upward; it is then said, the form springs, or it is termed the spring of the form.

In this case it is advisable to examine the furniture, for some pieces may not be planed square by the joiner, and to change them for others of the same size that appear perfect, and do not lock up very tight; tighten the quoins gradually, and frequently plane down while you are locking up; these measures will generally remedy the evil.


spring-back

norm: spring-back

text:
See illustration</> 1. A device or technique invented by the Englishmen John and Joseph Williams, in about 1799 and used ever since in the binding of large blankbooks. The spring-back consists of a strip of millboard, or other hard binder's board, the length of the boards of the book and of a width that, when curved, will fit around the spine and onto the sides of the text block at least one fourth of an inch on both sides. The board is first soaked in water and a strip of kraft paper four times its width is then glued around it. The purpose of the paper is to stiffen the board further so that it will maintain its form after it is curved to the proper shape. The assembly is curved around a core (the thickness of the book), or by means of a BACK-MOLDING IRON. A cloth liner is then glued to the interior of the curve, overlapping the edges by inches on either side. These overlaps are glued to the LEVERS. After the spring-back is attached, both ends are softened, paste is applied, and the ends of the spring-back are bent over to form the headcaps.

The purpose of the spring-back is to cause the book to lie flat so as to facilitate its being written in. It acts as a spring, and its pressure on the sides of the book near the spine causes the book to snap open and shut. The levers assist in this snapping effect, which is enhanced by the fact that the machine direction of the lever boards is at right angles to the length of the spine.

sprinkled edges

norm: sprinkled edges

text: The head, or all three edges, of a book which have been cut solid and sprinkled, usually with an earth pigment, such as bole, dissolved in a non-spirit solvent. Sprinkled edges are intended to be decorative and to prevent the edges from appearing to be soiled. The technique has been used since the 16th century, generally on trade and edition bindings, ordinary library bindings, and also on dictionaries and similar publications. Venetian red has always been the color most often used, possibly because it does not clash with other colors, such as endpapers or the leather covering. A good deal of the early sprinkling is very fine and even, so much so that at first glance it appears to be a solid color.

STACK OF PAPER

norm: stack of paper

text:
When paper is received into the warehouse from the stationer, it is piled up in tiers of four, five, six, or eight bundles in each tier, and is called a stack of paper, or a pile of paper.

The warehouseman in piling his paper considers the height of his room, that he may not take up more of the floor than is absolutely necessary, to enable him to stow as much as possible: thus, if he receive one hundred reams, and has height, he will make a stack of six in preference to two or four or five. He crosses the joinings of the bundles in each tier to bind them together, as a bricklayer does in building a square pillar; and I have always found the stack strengthened by laying on every third or fourth tier a number of stout wrappers spread over the bundles.

Paper should never be stacked without interposing something between the bottom of it and the floor, to prevent any water that might accidentally be spilled coming in contact with it, which would certainly mildew and spoil it if it were not perceived at the first; and even then it would require a great deal of trouble to prevent it: where there are not regular stages made, some short pieces of old poling laid a little distance from each other upon the floor will answer very well.

Where there are no regular stages in a warehouse, substitutes, which answer the purpose very well, may be easily provided, by taking an old paper board, or any pieces of board, and putting three pieces of an old pole under each of them on which to pile the books.


stain

norm: stain

text: A suspension or solution of a dye or other coloring matter in a suitable vehicle. The principal difference between a stain and other coloring agents is that the former has little or no power to opacify; consequently, when applied to leather. for example, a stain imparts color while still allowing the grain pattern of the leather to remain clearly visible. The two types of stains most often used in coloring leather in restoration work are spirit stains, which are dyes dissolved in methylated spirit, and water-soluble stains, which are dyes dissolved in water. Those most often used today for this purpose are the synthetic dyes, such as those prepared from aniline tars. Spirit stains tend to give greater penetrating power and are faster drying than water-soluble stains. Both types are available in powder form, or as prepared solutions.

staking

norm: staking

text: The process whereby the fibers of a leather are separated to a degree, thus softening the leather and improving its feel and handle. The process involves flexing the skin, either by hand or machine. Staking by hand is done by pulling the skin in all directions across a blunt blade fixed in a stake. The staking machine consists of a table that is divided into two parts with an opening of about 10 inches between them. The machine is equipped with two jaws, one above and one below the table. The upper jaw has a rubber roll at its end, while the lower jaw has a bladed opening into which the roll of the upper jaw may sink. The operator slides a portion of the skin between the jaws, which then come together and pull back. As they do so, they force the leather to flex sharply over the blades of the lower jaw and around the roll of the upper jaw. The operator holds the skin in place against the backward movement of the jaws and shifts the position of the skin after each motion of the jaws. There are also machines with automatic clamps that hold the skin when the jaws are staking it. Instead of a roll in the upper jaw, some machines have a smooth blade which forces the skin into a slot; both blade and slot pull backward with the skin between them, flexing it sharply along their path.
