Another plan, more simple, is the following:—Having laid the pages as nearly as possible in their proper places on the stone, with a suitable chase around them, fold a sheet of paper which has been wetted for the work, or one of the same size, into as many portions as there are pages in the form, and, holding the sheet thus folded on the first or left-hand page of the form, one edge even with the left-hand side of the type, place the adjoining page so that its left side may be even with the right-hand edge of the folded paper, which will leave a sufficient space between the two pages to admit the gutter-stick, which should then be selected of a proper width to suit the form in hand, as follows:—In octavos, about a Great Primer less in width than the space between the pages, as determined by the above rule; in duodecimos, about a Pica less; in sixteens, about a Long Primer; and proportionably less as the number of pages are increased. Having thus secured the proper width for the gutter-sticks, cut them somewhat longer than the page, and holding one of them between the two pages, above the page-cord, close the pages up to it; then open the folded sheet so as to cover the two pages, and, bringing the fold in the paper exactly in the middle of the gutter-stick, secure it there with the point of a pen-knife or bodkin; the right-hand edge of the paper thus opened must be brought to the centre of the cross-bar, which determines the furniture required between it and the pages. Having thus arranged the margins for the back and fore edge of the book, proceed in like manner to regulate the head and foot margins, by bringing the near edge of the folded paper even with the bottom of the first page, and so placing the adjoining off page that its head may be barely covered by the off edge of the folded paper, which will give the required head margin. All other sections of the form must be regulated by the foregoing measurements, when the margins for the whole sheet will be found correct.
The greater the number of pages in a sheet, the smaller in proportion should the margin be: the folded paper, therefore, should lie proportionally less over the edge of the adjoining page, both for gutter and back, in a form of small pages than in one of larger dimensions. A folio may require the page to be half an inch nearer the back than the fore-edge; while a duodecimo may not require more than a Pica em.
In imposing jobs where two or more of the same size, requiring equal margins, are to be worked together, fold the paper to the size appropriate for each, and so arrange the type that the distance from the left side of one page to the left side of the adjoining one shall be exactly equal to the width of the folded paper, as before described.
Having dressed the inside of the pages, next place side- and foot-sticks to their outsides; being thus secured by the furniture, untie the pages, quarter after quarter, the inner page first, and then the outer, at the same time forcing the letter toward the crosses, and using every precaution to prevent the pages from hanging or leaning; and, in order to guard against accidents, when the quarter is untied, secure it with a couple of quoins.
LOCKING UP FORMS.
First, carefully examine whether the pages of each quarter are of the same length; for even the difference of a lead will cause them to hang. Test their exactness: place the ball of each thumb against the centre of the foot-stick, raising it a little with the pressure, and, if the ends of both pages rise equally with the stick, it is a proof they will not bind; then fit quoins between the side and foot-stick of each quarter and the chase. After pushing the quoins as far as possible with the fingers, make use of the mallet and shooting-stick, and gently drive the quoins along the foot-sticks first, and then those along the side-sticks, taking care to use an equal force in the strokes, and to drive the quoins far enough up the shoulders of the side- and foot-sticks, that the letter may neither belly out nor hang, and the lines be kept straight and even. Quoins should be slanted on one side only, but the edges should not be bevelled. The several quarters of a form should be partially tightened before either quarter is finally locked up; otherwise the cross-bar may be sprung.
Before locking up the form, plane the pages gently over all the face. If this be properly done, a second planing is hardly necessary, provided the justification is perfect and the pages are all of the same length. But, as this is seldom the case, the second planing can hardly be dispensed with.
It often occurs that the quoins, when locked up wet, stick so tight to the furniture as to render it troublesome to unlock them: in such cases, drive the quoin up a little, and it afterward unlocks with ease.
Before lifting a form after it is locked up, raise it gently a short distance, and look under it, to ascertain whether any types are disposed to drop out. If all is right, carry it to the proof-press, and pull a good proof. Then rub it over gently with a ley-brush, rinse it well, and place it in a rack, and deliver the proof, with the copy, to the proof-reader.
