MULTICOLOR PRINTING METHOD FOR SOFT PACKAGING RESIN FILM, PRINTING APPARATUS FOR THE SAME AND MULTICOLOR PRINT

摘要

PROBLEM TO BE SOLVED: To provide a multicolor printing method for resin film which reduces production costs, decreases environmental problems and improves labor environments, and provides a high-quality multicolor print.SOLUTION: A method of multi-coloring a resin film A-1 executes white printing by a gravure or flexographic printing system and printing other than white by an ink jet printing system. The method reduces production costs of the plate cylinder necessary for gravure printing, decreases environmental problems and improves labor environments by minimizing the used amount of organic solvents and provides high-quality multicolor prints.
