Excerpt from The Preparation of Drawings and Other Illustrations for Photo-Reproduction There is probably no other adjunct to the making of technical literature which is so little understood and so carelessly handled as the preparation of the necessary text illustrations. And yet a great many publications depend for their principal value upon the illustrations which accompany the text matter. It therefore follows that poorly rendered illustrations will detract not only from the appearance, but also from the usefulness, of a book or paper, as compared with illustrations neatly and clearly executed, correctly drawn as to details and legibly lettered. For the reproduction of line drawings many authors and publishers resort to the so-called "wax engraving process." Here the original, either a tracing, or a blue-print, or pencil sketch on detail paper, is photographed in the desired size upon the sensitized waxed surface of a copper plate. The outlines of the drawing are then scratched through this wax enamel down to the blackened copper backing by means of different sized gravers. The lettering on such a drawing is set up in type and stamped into the softened wax. The finished wax engraving is "electrotyped, " the film-like copper covering on the wax mold is backed with type-metal, mounted "typehigh, " and is then ready for printing.
