THE ARTofPRINTING

Printing is distinctly a social art. Setting type and striking off a number of impressions presuppose, in the first place, a community to read what is printed; and in the second place, that the information printed is of value to this community.

INTRODUCTION

Woodwork has been quite generally introduced into the high school and grammar school. With all the defects of the earlier presentation of the subject, not to speak of those in later efforts, it has made a surprisingly general appeal, and has met with unusual and deserved success. Some of the methods employed, tending to place a ban on originality and thought, have brought it far short of its possibilities in the aid of intellectual development. To a considerable extent the woodwork has not touched, as intimately as it might, the vital interests of the pupils and of the homes; and, by its own limitations, it has not had an especially strong social bearing. The need is not less woodwork but more original and thoughtful woodwork, and also a greater variety of other constructive work which touches more and wider interests and which may appeal to those not particularly adapted to that one line. In this way it will be possible to strengthen the places where woodwork is weak. So far experience with printing in school indicates that it makes quite as general and permanent an appeal as woodwork.

Printing makes this very strong appeal to the boys because, in the first place, the printshop comes as near to reproducing a great world industry in the school as any other line of industrial work. Instead of doing simply the “roustabout” work of the beginning apprentice the boys are put to work with the regular shop equipment, and soon are ready to begin turning out some printing. It is a common thing to hear a boy remark, “This is just the way they do it down town.” So they look upon printing as the workof real men, and feel that they are actually taking part in some of the activities that are potent in the affairs of men. It’s wonderful, the pull of this feeling of participation in the world’s work.

Besides this, there is probably no other line of Manual Arts work in which pupils, grade boys especially, get so practical a working knowledge of the actual shop work as in printing. This fact is often turned to good advantage by the boys, for there can scarcely be found a commercial printshop anywhere which is not glad to employ one or two boys during vacation time, if they know a little about the work and are interested.

There is the still further fact that printing offers the concrete embodiment of rules of punctuation, capitalization, syllabication, sentence structure, paragraphing, etc. It is an indisputable fact that work in the printshop influences in a remarkable way the disposition to observe good form and to follow the best usage in all such matters. It is a daily occurrence in the school printshop that some boy brings a text book or newspaper to exhibit what he considers a glaring disregard of some of these principles of composition.

Printing furnishes a distinctly different type of motor activity from woodwork, for it is the arrangement of certain unyielding forms within limited space to produce some desired effect.

In the matter of social significance printing is practically ideal. Almost every problem is a community project, that is, a number of pupils combine their efforts to produce it. Practically every task in the printshop is undertaken with the consciousness of real service to a greatnumber of people in the school or in the community at large.

It is interesting to note that among the boys in school, the genuine joy in the production of printed matter does not necessarily arise out of a sense of the commercial value of the product. The class that has printed and illustrated a little pamphlet of stories for the second or third grade are proud and happy immeasurably beyond the pride and happiness that would come from a job of office blanks worth so many dollars. In other words, they are happy to the extent that the quality of their work merits praise, and that they feel able to make others happy by their services.

The school paper is an enterprise of very much the same nature. It is a real influence and a genuine service performed for which they expect no individual return except in the appreciation of those they serve, and pride in the excellence of their work and the skill it shows. This is certainly a kind of training for which there is a distinct need just now.

There is no other one of the Manual Arts that can touch so intimately the varied classwork, interests, and activities of school life as does printing, especially when combined with bookbinding.

It brings a freshness and vigor to the elementary reading and language work; it touches the athletics and social activities through announcements, programs, and notices in the school paper; it becomes an important factor in the celebration of special days, and in the preparation of material bearing on them; and it bears an intimate and vital relation to art.

Another interesting development is in the relation of printing to the other lines of constructive work. It has proved extremely valuable to have the completed problems written up in descriptive articles by the pupils, and to have the best of these compositions printed.

THE ART OF PRINTING

Methods and Tools of Composition.

In printing, composition includes all the steps from receiving the copy until the type is set up, proofed, corrected, and made up into page forms.

This discussion presupposes a knowledge of spelling, syllabication, punctuation, paragraphing, etc., all of which good composition really includes. Practical rules bearing on these different phases may be found in various handbooks for the printer.

The first essential in printing is, of course, a quantity of type properly arranged.

Type is cast from a composition of metals—lead, tin, antimony, and sometimes copper. This composition is melted and poured into moulds the size and shape of the desired type.

Accuracy in Size of Type.Lead is used as the chief constituent of the composition, because it shrinks very little in cooling. This makes greater accuracy possible. Accuracy is an absolute essential in type, for thousands of pieces of metal must be held together in one form by a slight pressure at the sides and ends of the form.

Lead alone is too soft to wear well and to retain the shape of the type under the constant pressure of the printing press. Tin is added to give hardness, and antimony or copper to give toughness to the type metal.

Type Described.Type are small columns of the metal with a letter or character in relief on one end of each column, as at Fig. 1. The surface of this relief portion from which the letter or character is printed is called the face.

The various faces are distinguished by names applied by the foundries, as “Caslon Old Style,” “Engraver’s Old English,” “Banker’s Script,” etc.

The extreme length of type from the face to the foot is .918 inches, or about eleven-twelfths of an inch.

Fig. 1.

The column of metal on which the letter or character rests is the body or shank of the type (a, Fig. 1) and the distance which the body extends beyond the edge of the letter or character is the shoulder (b, Fig. 1).

On the side of the body next the base of the letter or character are one or more nicks (d, Fig. 1). The chief purpose of such nicks is to indicate the base of the letter or character, and thus to aid the compositor in keeping the type right side up without constantly referring to the face of the type.

To the manufacturer, these nicks indicate other things in addition to that mentioned above, but these need not be detailed here.

The size of the type has to do with the body, and signifies the vertical distance through the body, or the distance from the nick side to the opposite side, as from x to x´, Fig. 1.

Of course it is clear that among the large amount of type manufactured, there must be a great number of different faces on the same size of body; and that there may be two or three sizes of the same face on the same size of body.

In order to indicate a specific type, it is necessary to mention its size and the name by which that particular face is distinguished; as, “10 point Author’s Roman Wide,” “18 point Pabst Old Style,” “6 point Caslon Bold Italic,” etc.

The Point System.The type manufacturers of this country have adopted a uniform scale of sizes known as the point system. In this scheme, the unit or point is .0138 inches, or about one seventy-second part of an inch. The size of any type is so many points based upon this system. Twelve points constitute anem picawhich is the larger unit of measurement.

When the printer speaks of dimensions, like the length and width of a page, he says it is a certain number of ems or picas long and wide. An em pica is one-sixth of an inch; so a page three inches by five inches is eighteen by thirty ems pica.

Until comparatively recent years there was no definite standard of type sizes. Each foundry established its own standards. If a printer wished to use type from different foundries, it probably was necessary to make some troublesome adjustments with bits of paper or otherwise to get them to line properly. (Specimenof wordsout ofline.)

There was a sufficient similarity in sizes of type to justify the use of names to indicate certain sizes. The names used to designate the common sizes from 4½ to 12 point type according to the point system, are as follows:

1. This line is set in 6 point Caslon Bold.2. This line is set in 8 point Post.3. This line is set in 10 point Author’s Roman Italic.4. This line is set in 12 point Strathmore Old Style.

1. This line is set in 6 point Caslon Bold.

2. This line is set in 8 point Post.

3. This line is set in 10 point Author’s Roman Italic.

4. This line is set in 12 point Strathmore Old Style.

Some of these names, such as Nonpareil, Brevier, Long Primer, and Pica, are still in quite general use.

Not only is the height or depth of the body determined by the point system, but the width or set of the body (cc´ Fig. 1) is also cast on the point basis. There are no fractional points in the width of type made on the point set basis. Any number of letters or characters placed side by side make an integral number of points. This is called point set.

Also, in case a number of differently faced type with the same body are used in the same line, they are so cast that the different faces line with each other as well as if they were all of the same face.

The system goes still further and makes it possible to use different sizes of type in the same line without difficulty in alignment. This is done by making the lining of the different sizes vary by points, so that the difference caneasily be built in with leads and slugs, see page14. This line hasthree differentfacesand two sizes of type.

Spacing of Words and Letters.Quads and spaces are pieces of metal shorter than the type, and are used to make blank spaces between words and at the ends of lines shorter than the measure.

Fig. 2.

In any size of type there are four kinds of quads. Fig 2 shows the ends of the 8 and 12 point quads and spaces. An em quad is the square of the type body. The 10 point em quad is a square quad whose sides are 10 points wide. An eight point em quad is 8 points or one-ninth of an inch square.

An en quad of any size type is one-half the em quad of that size of type. A two em quad of any size type is equal to two of the square or em quads, and a three em quad is equal to three of the square or em quads laid side by side.

There are four of the thinner blanks in any size of type, known as spaces. The 3-em space is one-third of the em quad; the 4-em space one-fourth of the em quad; and the 5-em space is one-fifth of the em quad. The hair spaces are very thin spaces of copper and brass. These are very seldomly needed in general work.

The em quad must be clearly distinguished from the em pica. Every size of type has its em quad; but the empica is simply the 12 point standard unit of measurement.

Type Font.A quantity of the same size and face of type with an assortment of the various letters and characters which are used together is called a font. Sometimes fonts are designated by the number of certain letters they contain. A font may be mentioned as having so many capital A’s and so many small a’s.

Type may be bought in weight or job fonts. If bought by weight, it contains capitals, small capitals, small or lower case letters, including ligatures (ff, fi, etc.), figures, marks of punctuation, spaces and quads. Twenty per cent of a weight font is made up of spaces and quads unless otherwise specified. Job fonts are small assortments of type, where only small quantities or unusual faces are needed. Such fonts do not include small capitals, spaces or quads.

Fonts or parts of fonts come from the foundry wrapped in small packages. The capitals, the small letters, and the quads and spaces come, of course, in separate packages. The letters are arranged for the most part in alphabetical order; but there is an occasional insertion of a mark of punctuation or a thin bodied letter out of regular order to fill out a line.

In taking the type from these packages, the entire face side of the mass of type is wet with soapy water. Then, beginning with the first of the alphabet, a few letters are taken at a time and put into the proper boxes of the case. This is called laying the case.

Fig. 3. NEWS CASES.

Fig. 4. JOB CASE.

Type Cases.Type cases, Figs. 3 and 4, in which type is kept are of two general kinds, news and job. News cases are in pairs, the upper and the lower case, arranged to occupy a position one above the other on top of the stand or cabinet, Fig. 5. The upper case contains the capitals, small capitals, and an assortment of signs and symbols. The lower case contains the small letters, numerals, marks of punctuation, quads and spaces. The California job case is about the size of the lower news case and fits like a drawer into a stand or cabinet. It is arranged to contain both the capitals and lower case type, but is without boxes for the small capitals. By reference to Fig. 4, it will be seen that the left side of the job case is exactly the same as the entire lower news case, except that the compartments are smaller.

Fig. 5.

The right side of the job case contains only thirty-five boxes for capitals instead of forty-nine, as in the capital side of the upper news case.

It will be observed that the capital letters are in regularorder in the case with the exception of J and U. It is interesting to note that these two letters were the last to be added to the alphabet, and hence were simply placed at the last of the alphabet in the case.

In the lower case there is but little regularity of arrangement, except that the most commonly used letters occupy the most convenient and conspicuous places. The printer knows the locations of the various boxes, so that the picking out of a certain letter becomes almost purely automatic.

TYPE SETTING

In beginning to set type, the first tool the printer needs is the job stick, Fig. 6.

Fig. 6.

This is the receptacle into which the compositor places the type as he sets up the form, letter by letter. Sticks are made in great variety, and almost any length from six inches up. There are the simple, ungraduated stick, adjusted by the thumb screw; the marked and perforated stick for nonpareil adjustment by means of a lever, Fig. 6, and the non-adjustable stick for news or book composition.

The printer sets the stick the length of the desired line. This is done by placing into it a lead or slug, the desired length, and moving the clamp up against it tightly enough that the type will not easily fall forward, and yet loosely enough to allow the lines to be lifted from the stick without binding.

12 em 2 point LeadFig. 7.

Spacing of Lines.Leads (Fig. 7) are strips of metal ¾″ wide, and from one to five points, inclusive, in thickness. Strips six points and thicker are called slugs. Leads and slugs are used to space between the lines oftype, bearing the same relation to the lines as spaces and quads bear to the words. These strips are said to be labor saving when they are cut ready for use into definite lengths of pica or nonpareil variations. The standard lengths are from 4 to 25 ems pica. When not so cut, they are called strip.

12 em 6 point SlugFig. 7a.

A lead or slug generally of the thickness to give the required space between the lines, and of the length of a line, is placed in the stick, and the type is set with the top of the letter toward this lead. Then with the lead or slug in the stick and the stick in the left hand, the compositor stands upright at the case, picks out the letters and characters one at a time, and places them, nick out and face up, into the stick, beginning at the lower left hand corner. Fig. 8. As the type are put into the stick, they are held there by the thumb of the left hand. The method of holding the stick at the proper angle to prevent the type from falling out and to allow the thumb to do its work properly, is quite an art which it takes time to acquire.

Justifying lines.—The line of type reads from left to right the same as printed matter but the letters are inverted. It takes the beginner some time to accustom himself to this condition, but with practice, it becomes easy and convenient. Each word except the last in the line, is followed by a space, or a quad. In ordinary solid matter, that is matter without leads or slugs between the lines, the three-to-emspaces are used between words. But the line must come out evenly at the end without leaving a space or dividing a word improperly. This very seldom occurs in beginning work, so the young printer sets himself to the task of justifying the line, that is respacing it so as to remove the difficulty. Approved methods of spacing and justification may be found in the list of rules of composition on page25. Great care should be observed in getting each line as nearly perfect as possible before proceeding to the next, for in this way, much trouble and annoyance in correcting proof are avoided.

Fig. 8.

When a line has been thus finished and a lead put in above to support it, the compositor proceeds with the nextline exactly as before. It is wise for the beginner to leave all the work leaded, so as to simplify the operation of removing the lines from the stick. If it is desirable, the leads or slugs may be removed after the type is emptied from the stick. If the last line of a paragraph is not a complete line, it is filled with quads and spaces, but the spaces should never be placed at the end or between the quads.

Fig. 9.

To Remove Type: The Galley.When the stick is full or nearly so, the compositor lays it down and to remove the type catches the first lead with both thumbs, and the last lead with the first finger of each hand. Fig. 9. Then he slightly raises the first line. With the remaining free fingers pressing against the ends of the lines and pushing at the same time down against the stick, he lifts the typebodily and puts it into the galley. The first line should go against the closed end and should read from the lower side of the galley up. The closed end of the galley should always be at the right as the worker stands at the case.

The galley, Fig. 10, is a kind of rectangular brass tray open at one end, into which the compositor places the lines of type on removing them from the stick. Galleys are of various sizes for different kinds of work.

Fig. 10.

Lines and Borders: The brass rule.In case there are solid lines to be made in the printed matter, as in Fig. 11, this is done by use of the brass rule.

Fig. 11.

This, like leads, may be had either in the strip or in labor saving lengths; but unlike leads, it is type high, and isdesigned for the purpose of making lines, borders, etc., Fig. 12. It may be had in any thickness, but usually, a very thin face like a hair line or one point, is put on a heavier body. In such cases the rule is beveled from one or both sides and is said to be side-faced or center-faced (a and b, Fig. 12). Labor saving brass rule is made up in weight fonts, and may be had with or without mitres for the corners.

Fig. 12.

If a rule line shorter than the measure of the type line is to be made, the blank spaces at the ends of the rule are filled with leads, slugs, or quads of the same thickness as the body of the rule.

Rule for borders is put around the type form after it is finished. If the face of the rule is as thick as the body, as at c, Fig. 12, good corners are made simply by lapping one piece of rule over the end of the other piece which meets it at the corner.

If the face is thinner than the body, the rule in borders or panels must be side-faced unless there are mitres. The bevels of the side pieces of rule are turned in toward the type and those of the end pieces are turned out. The endrule laps over the ends of the side rules at the corners, as shown at a, Fig. 12.

Dotted or hyphen lines as seen in Fig. 11, are made by the use of leaders, which closely resemble quads in that they are of quad sizes. Leaders, however, are type high, and have either the dot or hyphen face—so many dots or hyphens to the em. It is not necessary to have a great variety of leader sizes, since with the point lining system, one size of leader can easily be lined with another size of type.

Spacing and Tying a Galley or Job of Type.When the compositor has finished setting the type and placed it into the galley, if it is an advertisement or small job, he proceeds to space it out by the use of leads and slugs to the required length. The form is then tied up.

Fig. 13.

It requires considerable care and skill to tie up a mass of type properly. The form is in the lower right hand corner of the galley. The compositor takes a cotton string and beginning at the upper left hand corner, he starts to wrapping the twine around the form from left to right, drawing it taut just before turning a corner. When the starting point has been reached, he pulls the twine down across the original end thus binding it firmly against the metal. After wrapping from three to six times about the form, a loop is left in the twine, which is forced by means of a composing rule, Fig. 13, or a lead, down between the type and the strands. This leaves a small piece of the end projecting as a convenience in untying. The next step is to take a proof.The galley is laid on the stone or a table, or the form may be slid from the galley to the stone, Fig. 18.

Fig. 14.

Fig. 15.

Taking a Proof.When the tied form has been placed upon the stone or proof press, it is inked by rolling a small rubber roller (Fig. 14) over it, the roller having been first well inked by rolling it over an inked piece of marble, slate or glass. Then the type is covered with a moist paper, the sponged side up, or a regular proof paper. If there is no proof press the proof planer, a smooth faced block of hard wood, with face covered with felt, Fig. 15, is laid on the top of the paper, and tapped squarely and firmly with the mallet. If the proof planer does not cover the form, its position is changed and the mallet used again. The impression left on the paper is the first proof. See proof marks, page27. In school, it is wise to have the pupils read their own proofs.

Fig. 16.

To correct a galley.Then with the marked proof before him, the compositor proceeds to correct. If only slight changes are to be made, such as turning an inverted letter or taking out a capital and putting in a lower case letter, such changes may be made without lifting the type into the stick. Often lines or words are transposed, or omissions or repetitions are discovered. Such errors necessitate respacing and overrunning, by which is meant the going over several lines respacing them and crowding a word out of one line into another in order to correct an error. In such cases, it is well to lift out into the stick, the lines involved. In the matter of taking out a letter, it is necessary only to press lightly at both ends of the line with the thumb and finger of one hand, raising the line about half way out of the form, and with the other hand to remove the desired letter and allow the line to slide back into its original position. Bodkins and tweezers are dangerous and useless instruments in most instances. After the changes indicated in the first proof have been made, a second proof is taken to make sure that all corrections have been made, and that no new errors have crept in. This proof should be submitted to the instructor for approval. It may be necessary to make a number of proofs before a perfect impression is gotten. In case of a sufficient quantity of matter to necessitate its division into pages or columns, the proof is taken in the galley without tying up, Fig. 16. The form is locked tightly in the galley by means of furniture and quoins, Fig. 16. This is somewhat like the lockup described on page32, except that furniture is placed only on one side of the mass of type.

Fig. 17.

Making up.When the corrections are made, the matter is properly divided, the page numbers and headings are placed, and the pages or columns are tied up. This process is called making up. Fig. 17. When the printer begins to make up, he has before him a long mass of type, as at Fig. 16. The length of the page is determined. It includes the page number, the running head, if there be one, and a nonpareil, or six point, slug at each end.

A page 18 ems wide might properly be 30 ems long. In this case, the measure would be 31 ems and a 31 em reglet, (see furniture page31) answers well for a measure, as will any long piece of furniture on which the desired length may be marked. An accurate ruler may be used to advantage. The length of the first page is usually less than the full measure and is somewhat arbitrarily determined. It is generally sunken about one-fourth of the page. After this page is tied up and moved aside, the page number, the running head and the slug are added to the remaining column of type and the measure applied for the next page. This is repeated until the final page is reached, which is usually somewhat less than the full measure.

RULES OF COMPOSITION

1. Spacing between words should appear as nearly uniform as possible, not only throughout the line but throughout the entire piece of work.

2. For solid, or unleaded matter, the em quad is used to indent the paragraph, and to follow a period except at the end of a line; the 3 to em space, between words in the absence of marks of punctuation other than the comma; the en quad, after a semi-colon and also after a colon when followed by a lower case letter, but when followed by a capital letter, the space should be slightly larger, perhaps two 3 to em spaces.

3. The indentation and spaces between words should vary according to the spaces between the lines. In case of two point leaded matter, the en quad should be used instead of the 3 to em space and other spaces should be correspondingly larger.

4. In justifying a line after the spacing has been doneaccordingto the above rules, spaces may be increased at kern letters, f, y, etc., between long words, and after semi-colons and colons; or reduced at slanting letters, at commas, and at the sides of small words. Spaces should be the same on both sides of very small words, and there should never be a greater variation in the spacing between ordinary words than the difference between an en quad and a 3 to em space.

5. Type should stand squarely on foot.

6. Divisions of words at the ends of the lines should be avoided wherever possible but when divided, the proper division of syllables should always be made.

7. Avoid dividing short words, or dividing words by cutting off short syllables at the first or last.

8. Do not loosen the clamp of the stick in order to make it possible to insert a space.

9. When in doubt about spelling, punctuation, capitalization, or syllabication, consult authority.

10. Save endless time and trouble by producing a clean proof the first time.

11. In making up, it is good form to have the first and last lines of a page full lines. So it is best not to have a paragraph begin with the first line or end with the last line of a page.

IMPOSITION

Imposition is the arranging of the type masses in proper order on the stone, and the fastening of them into the chase.

Fig. 18.—BACK VIEW.

Fig. 18.—FRONT VIEW.

The imposing stone, Fig. 18, is a smooth marble slab on which the forms are placed for locking up ready for the press. The stone may be laid upon a box, bench or table, but both stands and cabinets are made for this purpose. It is properly bedded in its “coffin” by placing putty along the edges of the bed and along any cross supports which may run under the stone. Then when the stone is placed into this receptacle, it remains solid and level and free from strain. It should project a short distance above the frame of the bed in order to render easy the removal of the forms to and from the galley.

Fig. 19.

The chase, Fig. 19, is a steel or cast-iron frame, into which the forms are locked to be put into the press. The size of a press is based upon the inside dimensions of the chase. A 10 × 15 press is one that accommodates a 10 × 15 chase. The skeleton chase is a steel chase with a very narrow frame. This makes the inside considerably larger. A skeleton chase for a 10 × 15 press is practically 11 × 16, making a clear gain of almost an inch each way.

When the type has been proofed, corrected, made up, and tied, the form is slipped from the galley to the stone, and is then ready for the lockup, Fig. 20.

Fig. 20.

A chase is put upon the stone in such a position as to form a frame about the type, which as a rule should occupy the central part of the space enclosed by the frame. A roller supporter, a, Fig. 20, is placed in each end of the chase and pieces of furniture are built out solidly from the type form to one side and one end of the chase.

Fig. 21.

Furniture, Fig. 21, and b, c, Fig. 20, is the name given to pieces of wood and metal, which are used to build around the forms in the process of locking them into the chase. Furniture varies by the em in width and by 5 to 10 ems in length when cut labor saving. Metal furniture is more modern and makes possible more accurate work; but for beginners, it has its disadvantages. The metal is soft and of considerable weight, making heavier forms; and if a piece is dropped upon the stone or even upon the floor, which frequently happens, it probably has a corner or an edge battered. In the lockup, occasionally this small defect may cause the “pi” of the whole form. Reglets are a kind of wood furniture similar in size and use to leads and slugs but are largely used as furniturein locking up forms. In leaded forms which have to be kept for sometime, reglets are substituted for the leads and slugs. They are very much cheaper, and they relieve the necessity for large quantities of the more expensive leads and slugs. Wood furniture, which comes by the case or by number of pieces, is cheap, durable, not easily injured, and on the whole, quite satisfactory for school use. A small amount of metal furniture, which is sold by weight, is desirable in every printshop.

When the furniture has been built in at one side and one end of the form as indicated above, quoins are placed at the other side and the other end about midway between the type and the chase.

Fig. 22.

Quoins, Fig. 22, are devices for locking the forms into the chases. There are two chief kinds, one consisting of two separate wedge shaped pieces of hard metal with notched sides, which by the use of a key are made to slide in opposite directions against each other. The danger of these quoins in the hands of schoolboys is that, not realizing how easily good forms are held, they persist in trying to screw the quoin to the last notch, frequently endangering the chase and ruining the quoins. The other kind is constructed of two pieces of metal joined by springsand opened by the use of a key operating a nut which, after a slight expansion of the quoin, releases its hold and allows the parts to spring back together. This quoin is safe for the form and for the chase, and is itself not battered in the process of locking up.

After the quoins have been put into proper position, pieces of furniture are fitted in on both sides of the quoins.

The pieces of furniture are usually a little longer than the sides of the form against which they fit. They are always placed around the form in such a way that they can not bind against each other so as to prevent the pressure from striking the type squarely, Fig. 20.

With the key, Fig. 22, the quoins are very slightly and uniformly tightened. Then the planer is used.

Fig. 23.

The planer, Fig. 23, is a smooth faced block of hard wood similar to the proof planer, but is usually smaller and not covered with felt. This is laid on the face of the form on the stone and tapped lightly with a mallet, in order to make sure that the faces of all the type are at the same level—no letters projecting so as to be broken or to injure the rollers, or, at best, to ruin the impressions.

After this, the printer tightens the quoins gradually, giving a slight turn to each quoin in succession. There is danger of the beginner’s getting the lockup too tight, causing the form to spring up from the stone and the chase to spring and even to break. If the composition is good and the furniture is properly placed, it does not require avery tight lockup to hold. Before removing the chase from the stone, the lockup should be tested by raising one side of the chase very slightly and tapping the furniture to see if any of the type are loose. If the form holds, it is ready for the press.

Forms for Four and More Pages.When there are a number of pages instead of one to be dealt with, the imposition is considerably more complicated.
