While this is true in regard to a design for a text letter, the design for a display type is often made to attract attention, not only to itself, but to what it proclaims, by its boldness and beauty and sometimes even by its ugliness.
After the design has been drawn, it is placed in a "delineating machine," where an enlarged outline pencil copy, or tracing, is made, so large that all errors are easily seen and corrected. New designs may, however, be drawn in outline by hand on the enlarged scale, thus rendering unnecessary both the pen-and-ink drawing and the tracing.
With the aid of the delineating machine, the operator, besides being able to produce an accurately enlarged outline pencil tracing of a design, is also enabled, by various adjustments, to change the form of the pencil tracing in such a manner that it becomes proportionately more condensed or extended, and even italicized or back-sloped. That is, from a single design, say Gothic, pencil tracings can be made condensed, extended, italicized, and back-sloped, as well as an enlarged facsimile.
The next operation consists in placing the enlarged outline pencil drawing in a machine which enables the operator to reproduce the outline drawing, reduced in size, on a metal plate, evenly covered with wax, with the line traced entirely through the wax. The plate is then covered with a thin layer of copper, electrically deposited, and is "backed up" with metal, and trimmed and finished, similar to an ordinary electrotype plate of a page of type. A copper-faced metal plate is thus produced, on which are the raised outlines of a letter. This is called the "pattern." From this pattern all regular type sizes may be cut. It determines the shape of the letter, but the size and variations from the pattern are determined later by the adjustments of the engraving machine in which it is used.
The pattern is now sent to the engraving room. Machines have superseded the old-fashioned way of cutting punches and originals by hand, and they have enormously increased the production of new type faces. Whereas in the old days it took about eighteen months to bring out a new Roman face, or style of letters, in seven different sizes, to-day it can be done in about five weeks. The reason is that formerly only one artist, known as a punch-cutter, could work on a single face, and he had to cut all the sizes, otherwise there were noticeable differences in style. By machine methods, where all sizes can be cut simultaneously, it is only a question of having the requisite number of engraving machines.
As to the quality of machine work, it is superior to hand work both in accuracy and uniformity. The artist formerly cut the punches, or originals, by hand under a magnifying glass, and the excellence of his work was really marvellous. However, when changing from one size to another, there were often perceptible variations in the shapes of the letters, or the sizes were not always evenly graded. By the machine method the workman uses the long end of a lever, as explained below, and has therefore a greater chance of doing accurate work. In addition to this, a rigid pattern forms the shape of the letter, and to it all sizes must conform.
Another gain the machine has over hand-cutting is its greater range. When the old-time artist made an unusually small size of type for Bible use, he did it with great strain on his eyes and nerves. At any moment his tool might slip and spoil the work. With the machine, on the other hand, and with no physical strain whatever, experimental punches have been cut so small as to be legible only with a microscope—too small, in fact, to print. At present there are two styles of engraving machines employed,—one cutting the letter in relief,—called a "punch" if cut in steel, and an "original" if cut in type metal,—and the other cutting a letter in intaglio,—called a "matrix." Both machines are constructed on the principle of the lever, the long arm following the pattern, while the short arm moves either the work against the cutting tool, or the cutting tool against the work. The adjustments are such that the operator is enabled to engrave the letter proportionately more extended or condensed, and lighter or heavier in face, than the pattern. All these variations are necessary for the production of a properly graded modern series containing the usual sizes. In fact, on account of the laws of optics, which cannot be gone into here, only one size of a series is cut in absolutely exact proportion to the patterns.
As it is impossible to describe these machines clearly without the aid of many diagrams and much technical language, only a brief description of their operation will be given.
When the letters are to be engraved in steel, blocks or "blanks" are cut from soft steel and finished to the proper size. A blank is then fastened in the "holder," the machine for cutting the letter in relief adjusted to the proper leverage, and the pattern clamped to the "bed." The long arm of the lever, containing the proper "tracer" or follower, is moved by the operator around the outside of the pattern on the copper-faced metal plate, causing the blank to be moved by the shorter arm around and against a rotating cutting tool. This operation is repeated several times with different sizes of tracers and different adjustments to enable the cutting tool to cut at different depths, until finally a steel letter in relief is produced, engraved the reverse of the pattern and very much smaller. After being hardened and polished, this is called a steel punch, and, when driven into a flat piece of copper, it produces what is known as a "strike" or unfinished matrix.
If in the same machine type metal is used for blanks, the resulting originals are placed in a "flask," or holder, and submerged in a bath, where they receive on the face of the letter a thick coating of nickel, electrically deposited. As soon as the deposit is of sufficient thickness, they are removed and the soft metal letters withdrawn, leaving a deep facsimile impression in the deposited metal, which also is an unfinished matrix.
