In the olden time the engraver, or etcher, himself was to a considerable extent his own printer. He worked at engraving his plate until he needed a proof to show him how the work was progressing. Then he printed, or "pulled," a proof and resumed his work, taking proofs from time to time until he had completed the plate to his satisfaction. Then, if only a small edition was required, he printed it. Proofs taken during the making of a plate are known by plate engravers and printers as the "states" of a plate, and it is due to the whim of the etcher, the softness of the copper, and the wearing of the plate in printing that we have prints representing many "states" of a single plate which might otherwise have had but one state, thus depriving one modern print collector of the privilege of discovering in his proof three hairs more or less in a donkey's tail than his rival finds in another proof, which makes the former's more valuable by several hundred pounds.

One form of press is used for all manner of intaglio plate printing. It consists of a framework supporting two heavy iron rollers, between which moves a flat iron travelling plank, or bed, and on this bed the plate to be printed is laid. The pressure of the rollers is regulated by screws at each end of the top roller, which is covered with two or three pieces of thick felt. This top roller is revolved by handles and the bed moves along with it under the pressure of the roller. At one side of the press stands a rectangular box, or "stove," made of iron, or having an iron top. The top is heated by gas and on it the printer puts his plate while inking and wiping it. The heat thins the ink as it is applied, allowing it to be worked freely and to be "lifted" easily by the paper.

The ink is made of fine bone dust, vegetable or other form of carbon, which has been carefully cleansed from foreign matter and ground to the necessary fineness in combination with burned linseed oil. Its strength and consistency should be varied according to the plate which is in hand, and the color also may be varied to suit the character of the plate by the addition of pigments.

The paper used in plate printing may be one of several kinds, but the usual variety is a fine white paper free from spots and imperfections which might mar the appearance of the finished print. This paper is made either by hand or machinery of selected bleached cotton rags, and has a soft, spongy surface which yields readily under the pressure of the plate. Before it can be used the paper is moistened and allowed to stand for from one to twelve hours, or even longer, until it becomes evenly and thoroughly dampened,—but not wet,—so that it will more readily force itself into the lines of the plate and take therefrom and hold the ink.

Before printing a photogravure, mezzotint, or other engraved plate the printer must first carefully examine it to see that it has no scratches, and that no dried ink remains in the lines from the last printing, and, in fact, that there are none of the many possible impedimenta which might prevent the production of a perfect print. The plate being in proper condition, it is then thoroughly cleansed with turpentine or benzine, all traces of which must be carefully wiped from the surface before the ink is applied. The plate is then laid on the heated iron box or "stove" until it has become thoroughly warmed. The surface of the plate is covered with ink, put on by means of an ink-roller, or perhaps the old-fashioned dauber, and the ink is thoroughly worked into the lines or depressions in the plate. After this the ink on the flat surface of the plate is entirely removed by wiping with rags. The printer's hand, which has become more or less covered with ink from the rags, is then passed over a piece of chalk, or gilder's white, and lightly rubbed over the surface of the plate, to remove the last vestige of the ink, leaving a highly polished flat surface with the incised lines or depressions filled with ink to the level of the surface.

The plate is then ready for printing and is placed on the bed of the press, a sheet of dampened paper laid upon it, and both are then run between the rollers of the press. As the top roller is encased in soft blankets, the soft, dampened paper is forced into the ink-filled lines of the plate, and when the paper is removed the ink clings to it and shows an exact impression of the engraving. This entire process must be repeated for each print made from an intaglio plate.

While the printing of a steel engraving or photogravure is a more or less mechanical operation, the printing of an etching—and "dry points" may be included—is oftentimes as much of an art as the actual etching of the plate. The two styles of printing may be compared to two kinds of fishing,—that of fishing for flounders with a drop line, from a flat-bottomed boat at low tide when one must just sit tight until one has a bite, and then haul in the fish, bait up, drop the line and wait again, as against that of angling for trout on an early spring day, dropping the fly in a likely spot without success at the first cast, persevering until rewarded by a rise and then by the sport of playing the fish, giving him line and reeling him in as about he circles and finally is landed. A good one, perchance, but the sport was in landing him. So it is with printing an etching. There is the opportunity to play with, and work hard over, a plate. Perhaps the etcher has not, for reasons only known to himself, put in the plate all that can be shown in the print by ordinary printing. The printer actually has to interpret in his printing the etcher's meaning, for the which, as a rule, he gets "more kicks than ha'pence," and in the end wishes he had stuck to plain plate printing as far as the profit is concerned.

In the process of printing an etching, the printer first covers the plate with ink and then wipes it with the rags, and, if necessary, with the hand. It depends entirely upon the etched work of the plate as to how it must be wiped, and it rests with the printer to prepare a proof which is satisfactory to the etcher. The plate is wiped "closely" where the high lights are required or a tint (a thin coating of ink) left over certain portions where it needs to be darker. After this the plate is "retroussed," which is accomplished by passing a very soft piece of fine muslin, or a "badger blender,"—a soft brush used by artists,—delicately over the work in the plate and drawing the ink up and over the edges of the lines. This softens and broadens the lines and gives a very rich effect, and, if continued sufficiently, fills the spaces between the lines and produces an almost black effect. All this work is varied according to the wishes of the etcher. A plate that left the etcher's hand a mere skeleton may be made to produce a print which is a thing of life. The possibilities of an etching in the hands of a skilful printer are almost limitless; the effects can vary with every impression, each showing a new picture. His processes are as interesting as those of the etcher himself, and it is within his capabilities to transform an etching from a broad daylight effect into a moonlight scene, including the moon, by judiciously, or injudiciously, inking and wiping the plate.

A "dry point" plate is produced by drawing on a copper plate with a steel or diamond point, and without biting by acid. The lines are cut into the copper and a burr thrown up which holds the ink in printing, and produces a soft, velvety line. The method of printing such a plate is similar to that of an etching, but the possibilities are not as great in the printing, as they rest to a greater extent upon the work of the artist. A great depth of color, producing wonderfully rich effects, can be obtained and the finer lines can be made much more delicate than by any other method.

The printing of intaglio plates in color flourished for a short period in the latter portion of the eighteenth century, and the best prints of that time now in existence are of rare beauty and bring enormous prices. The process, now almost a memory, is a costly one, and this prevents its use in book illustration excepting for volumes which command a very high price. This kind of printing requires the plate to be actually painted by hand with inks of such colors as the picture may require, and the painting has to be repeated for every impression that is taken. The colors are put on with a "dole,"—a small piece of muslin turned to a point,—and great care must be taken that they do not overlap, or run into, each other. As each color is placed, the plate is wiped clean with rags as already described, and when all the colors have been properly placed, the plate is pulled through the press in the same manner as in ordinary printing.
