MULTICOLOR OFFSET PRINTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a multicolor offset printing system which is a simplified method in place of a conventional multicolor off set printing method using a silver salt type film and can obtain a good clear multicolor printed matter without causing undesirable color dislocation and overlap in the marginal part of duplex printing and the boundary part of different colors. SOLUTION: A process is provided in which characters or image data are printed by an ink-jet method on a synthetic paper sheet or a film in which an ink receiving layer is formed to make a block copy, from which an offset printing plate is prepared.
