Abstract

582,580. Printing-surfaces. BOLL, O. May 4, 1944, No. 8474. [Class 100 (ii)] [Also in Group XX] In a method of producing printing-plates for use in photolithography, photo-engraving and similar processes, a sheet of backing- material of a non-metallic nature such as an artificial resin, paper, cardboard or fabric is grained or rendered matt by sand-blasting or scouring, and a metallic layer consisting of a. metal other than chromium is applied thereto by spraying or by electrodeposition. The applied metal surface is smoothed by placing the plate in a shaking-frame and subjecting the surface to the action of sand and water, with the aid of pebbles, marbles or the like, if necessary. The metallic layer may be of zinc, copper, aluminium, or bronze. The backing-material may be rendered waterproof by the application of an oily material or an artificial resin.
