Abstract

25,257. Miller, F. R., and Millergraph Co. Nov. 4. Photo-mechanical printing-surfaces; negatives, producing by means other than photography.- For making photo-mechanical printing negatives and positives, a transparent sheet of gelatine, celluloid, or the like is roughened by forming a number of tapering projections on one surface. The roughened surface is then coated with varnish, gum, or other material to render it opaque. The negative is drawn by hand or printed and is worked up with a scraping-tool by means of which light holes of varying size are formed according to the depth to which the tapering projections are cut. If the negative is to be traced, the sheet is coated with material to render it semi-opaque only. The negative is used for producing a photo-mechanical positive.
