Abstract
653,292. Multicolour printing. MINISTER OF SUPPLY. Nov. 26, 1948, No. 30682. Drawings to Specification. [Class 100 (ii)] In multicolour printing, either the transfer surface receiving the complete colour picture from the colour separation plates, or the impression surface if the colour separation plates print direct on to the paper, has a pattern corresponding to a complete colour picture and made from a positive or negative produced by exposure through a colour reseau. In a rotary printing machine the rollers carrying the colour separation plates are provided with micrometer adjustment both axially and angularly to effect accurate registration ; the invention is also applicable to printing from flat plates. The transfer or impression surface and the colour separation plates may be produced by a photographic half-tone process, e.g. an engraved or etched flat steel plate may be thus produced and a roller carrying a type metal block rolled over it with sufficient pressure to impart the pattern corresponding to the elementary areas of the reseau.
