Abstract

168,578. Renck, H. Sept. 2, 1920, [Convention date]. Photo-mechanical printing-surfaces. - In the production of gelatine relief printing-surfaces, the exposed film is soaked, to swell the unexposed gelatine, hardened, and is then submitted to a heat treatment up to from 40‹ to 60‹ C. in order to cause the swelled parts to sink below the level of the hardened exposed parts, thereby giving a relief printing surface. In the Specification as open to inspection under Sect. 91 (3) (a) the method of heat treatment by pouring a heated mass upon the swelled gelatine surface is described. This subject-matter does not appear in the Specification as accepted.
