The Building of a Book / A Series of Practical Articles Written by Experts in the Various Departments of Book Making and Distributing

Let us consider briefly the different kinds of book cloths that are most commonly used to-day and try to make clear to the lay reader the different fabrics, whose nomenclature is so frequently confused even by binders and publishers.

Book cloths, from their appearance and manufacture, fall into two natural divisions, the first being the so-called "solid colors," in which the threads of the cloth are not easily distinguishable. This division contains two grades of cloth, generally known as common colors and extra colors. The standard width of all book cloths is thirty-eight inches. The commons and extras are sold by the roll, and the standard number of yards to the roll of these fabrics is thirty-eight.

The second division consists of the so-called "linens" and "buckrams," in which each thread, with the imperfections and peculiarities of the weaving, are plainly seen and form a large part of their picturesque effect.

The first of the "common colors" to be used was the black cloth already referred to, but they are now made in many colors, though chiefly in simple, pronounced shades, such as browns, blues, greens, and reds. These cloths have been dyed, and sized with a stiffening preparation. They are the cheapest of the solid colors and are used in various patterns, which are embossed on the surface during the process of manufacture.

The ordinary patterns which are in the greatest use to-day are designated in the trade by letters. Perhaps the most familiar is the "T" pattern, straight parallel ridges or striations, about forty to the inch, and running across the cloth from selvage to selvage. When properly used, these ribs run from top to bottom of a book cover. For this reason it is not economical to use the "T" pattern if the height of the cover is not a multiple of the width of the cloth, as it results in a waste of cloth. This explains why the cost of the book bound in "T" pattern is frequently somewhat higher than the same book bound in another pattern of the same cloth.

A similar design is the "S" or silk pattern, made up of finer lines running diagonally across the cloth, giving the surface a sheen somewhat resembling silk. Also in common use are a group of patterns composed of small irregular dots or points, the finest of which is known as the "C" pattern, a coarser pattern of similar design, the "J," and, coarser still, the "L," which has somewhat the appearance of the coarse grain of a morocco leather. The pattern known as "H" is a simple diamond made by intersecting diagonal lines similar to the ribs of the "T" pattern. Other patterns in less common use are those resembling morocco leather, pigskin, and patterns in fancy designs.

Following the increased use of the common cloths, attention was given to the artistic effects which might be obtained by using colored inks and gold on lettering and design, and also to the effect obtained by pressure of hot binders' dies or stamps upon covers made with embossed cloths, which latter process is known in binding as "blanking" or "blind" stamping.

With these advances in the art of cover decoration came the demand for the more delicate tints and richer shades of the colors, and as a result finer colors than could be produced in the common cloths were introduced to meet this demand; these fabrics were called the "extra" cloths. They have a solid, smooth surface, more "body," and are in every way firmer and better fabrics, and more costly, too, some of the shades costing from twenty to forty per cent more than the common cloths.

Extra cloths are used largely on the better class of bindings, such as the popular fiction, holiday books, scientific books, and books of reference, and whenever fine coloring or a better appearance is desired. These cloths are chiefly used in the plain fabric, which is known as "vellum," and in the "T," "S," and "H" patterns. The trained eye easily recognizes extra cloth from the common cloths, by the appearance of the surface; but any one may readily distinguish them by the appearance of the back, which in the extra cloths is not colored, but in the commons is the same color as the face.

Of the second division of cloths, in which the appearance of the threads becomes a part of the effect, there are first the "linen" cloths. The name "linen" applied to this group is really a misnomer, for many laymen are led to think that such cloths have flax as a foundation and are therefore genuine linens. This is not so, for there is but one genuine linen book cloth to be had, and that is a coarse, irregularly woven cloth, dyed in dull colors, and manufactured by a foreign house. It is quite expensive, costing sixty cents a square yard, which is one of the reasons why it is seldom used.
