rests in properly collating the book, in guarding maps, and in
placing the plates. When pasting in any single leaves or
plates, a piece of waste paper should always be placed on
the leaf or plate the required distance from the edge to be
pasted, so that the leaf is pasted straight. It takes no longer
to lay the plate down upon the edge of a board with paper
on the plate, than it does to hold the plate in the left hand,
and apply the paste with the right hand middle finder; by the
former method a proper amount of paste is deposited evenly
on the plate and it is pasted in straight line; by the latter
method, it is pasted in some places thickly, and in some
places none at all. I have often seen books with the plates
fastened to the book nearly half way up to its foredge, and
thus spoit, only through the slovenly way of pasting. After
having placed th plates, the collater should go through them
again when dry, to see if they adhere properly, and break or
fold them over up to the pasting, with a folding stick, so that
the whole of binding, especially after pressing. The amount of gum that is put on the surface, which is very easily
seen by the gloss, causes them to stick to the letter-press: should they so stick, do not try to tear them apart, but
warm a polishing iron and pass it over the plate and letter-press, placing a piece of paper between the iron and the
book to avoid dirt. The heat and moisture will soften the gum, and the surface can then be very easily separated. By
rubbing a little powdered French chalk over the coloured plates before sticking them in, these ill effects will be
avoided.
It sometimes happens that the whole of a book is composed of single leaves, as the "Art Journal." Such a book
should be collated properly, and the plates placed to their respective places, squared and broken over, by placing a
straight edge or runner about half an inch from its back edge, and running a folder under the plate, thus lifting it to
the edge of the runner. The whole book should then be pressed for a few hours, taken out, and the back glued up;
the back having been previously roughed with the side edge of the saw. To glue such a back, the book is placed in
the lying press between boards, with the back projecting about an eighth of an inch, the saw is then drawn over it,
with its side edge, so that the paper is as it were rasped. The back is then sawn in properly, as explained in the
next chapter, and the whole back is glued. When dry, the book is separated into divisions or sections of four, six, or
eight leaves, according to the thickness of the paper, and each section is then overcast or over sewn along its
whole length, the thread being fastened at the head and tail (or top and bottom); thus each section is made
independent of its neighbour.
The section The sections should then be gently struck along the back edge with a hammer against a knocking-down
iron, so as to embed the thread into the paper, or the back will be too thick. The thread should not be struck so
hard as to cut the paper, or break the thread, but very gently. Two or three sections may be taken at a time. After
having placed the plates, the book should be put into the press (standing or otherwise) for a few hours. A standing
press is used in all good bookbinding shops. The Paris houses have a curious way of pressing their books. The
books are placed in the standing press; the top and bottom boards are very thick, having a groove cut in them in
which a strong thin rope is placed. The press is
screwed down tightly, when, after some few minutes has elapsed, the cord or rope is drawn together and fastened.
The pressure of the screw is released, the whole taken our en bloc, and allowed to remain for some hours, during
which time a number of there batches are passed through the same press. When taken out of the press the book
is ready for "marking up" if for flexible sewing, or for being sawn in if for ordinary work.
