METHOD FOR MANUFACTURING ORIGINAL PRINTING PLATE FOR LITHOGRAPHIC PRINTING

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an original printing plate for lithographic printing successively providing at least a hydrophilic layer and an image forming layer by a coating method using a coating apparatus which does not generate scuff marks, generates no precipitation of a filler in the coating apparatus, and can continuously coat for a long time, when a coating is performed by using a coating liquid containing the filler on a belt-like plastic film substrate (hereinafter called the substrate) continuously carried.

SOLUTION: In the method for manufacturing the original printing plate for lithographic printing successively providing at least the hydrophilic layer and the image forming layer by applying the coating liquid containing the filler on the belt-like plastic film substrate continuously carried by using a coating apparatus, the method for manufacturing the original printing plate for lithographic printing is characterized by the coating apparatus being an atomizer type spraying apparatus.
