PRINTING METHOD OF PROCESS-LESS PRINTING PLATE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a printing method employing process-less printing plate material, in which plate wearability is improved than ever and the fouling with ink is little.

SOLUTION: This printing method is to perform printing after the removal of a non-image part by supplying dampening water having not more than 0.01 mol of the content of a phosphoric acid compound with a pH of at least 4.5 and not more than 8 per 1 litre of the dampening water and ink onto the surface of the printing plate material under the condition that the printing plate material having an image forming functional layer on a base material with a hydrophilic surface is image-wise exposed and then mounted to a printing machine.
