Practical Bookbinding

by Paul Adam

For use as end papers, a paper must be selected which suits in quality and tone the printed paper. Nothing shows lack of taste more than the use of a blue end paper with a paper of yellow tone. For both back and front a double sheet is necessary and is cut the required size. A paper guard, about the width of three fingers, is made from a piece of stout waste paper and pasted on a narrow margin at the back of the double leaf, in order to protect it in the joint and also for fastening on the cover. If there are single leaves to be used up, two of these might be pasted to each other narrowly on the back and upon this the guard; this is the so-called double end paper.

If instead of these only a single leaf is taken, then we have a single end paper; this is used for cheap school books and generally at the back only.

The accompanying sketch shows both these end papers with the small guard already folded. This folding of the guard is not very easy for the beginner. The leaf is placed face upwards, square in front of the worker, and a very narrow margin at the back edge bent upwards about 3 mm. in width, the forefinger and thumb of both hands shaping and bending the guard, working from the centre to the ends.

Fig. 25—Suggestions for single and double end papers.

Should the sheet from which the end papers are made be a little wider than required for the end papers, the tear-off may be folded at the same time; with double end papers, the leaf which is to be pasted down later is inserted between fly leaf and tear-off, and therefore is called "insertion."

If the end papers are to have a cloth joint it must be placed within the two leaves or, better, pasted in face inwards. Double cloth joints are no longer used in printed books, as they make the end papers too thick, and in the subsequent rounding the first sheet is apt to break. The joint is here also folded on as before.

Formerly, when linen joints were used, the end paper was simply made by inserting the strip of cloth and hingeing on the outside leaf about 1 cm. from the fold. This, however, has many disadvantages, therefore the end papers are made as explained, then carefully tearing off the outside leaf in the back in pasting down and cutting it as required it is pasted on to the board, as will be more fully explained under "pasting down."
