Abstract
427,407. Photo-mechanical printing- surfaces. HURST, R. E., 116, Chadbourne Road, and MEULENDYKE, C. E., 1011, University Avenue, both in Rochester, New York, U.S.A. Oct. 18, 1933, No. 28874. Drawings to Specification. [Class 98 (ii)] A metallic sheet is coated with a silver salt emulsion of sufficient sensitivity for contact printing or for direct exposure in a camera ; and after exposure and development of the silver image a negative or a positive colloid relief is produced, under the selective control of the silver image, to serve as a resist for the metal by which to obtain a printing plate. The metallic sheet may be a copper base sheet plated with nickel or chromium or other metal inert to the emulsion layer, i.e. a metal which does not contaminate the emulsion and protects it from contamination by the copper base. The surface of the nickel &c. layer is preferably grained. Alloys may be used as well as pure metals or two or more layers of different metals, for example, a nickel layer coated with a thin layer of chromium. The developed image is converted into a negative colloid relief by a bichromate in solution (or other tanning agent) or into a positive by an oxidizing agent such as hydrogen peroxide or persulphate. The plate may then be etched through the inert metallic layer into the base plate in those parts unprotected by the emulsion resist.
