MULTI-COLOR IMPRESSION PRINTING DEVICE, MULTI-COLOR IMPRESSION PRINTING METHOD AND PRINTING REGISTER MARK

摘要

PROBLEM TO BE SOLVED: To provide a multi-color impression printing device which can precisely perform a printing registration process, even when meshy cells with a mutually different screen angle are formed in the surface of each plate cylinder, and a multi-color impression printing method and a printing register mark.;SOLUTION: Each printing means 10a, 10b, 10c and 10d puts register marks 40a, 40b, 40c and 40d to a printing substrate W. Each register mark 40a, 40b, 40c and 40d is slant respectively according to the screen angle of each plate cylinder 11a, 11b, 11c and 11d to the feed direction of the printing substrate W. A registration means 30 performs a printing registration process so that each positional relationship between the specified spots 42a, 42b, 42c and 42d of the register marks 40a, 40b, 40c and 40d detected by a register mark detection means 20 can be kept uniform.;COPYRIGHT: (C)2006,JPO&NCIPI
