PHOTOSENSITIVE PLANOGRAPHIC PRINTING PLATE AND FABRICATION PROCESS THEREOF

摘要

A photosensitive planographic printing plate which can avoid quality defects such as residue films and the like and improve yield, and a fabrication process thereof. A coating layer of a region corresponding to an edge portion of a PS plate is preparatorily cleared by coating removal. Hence, pressure fogging which is formed by pressure at a time of cutting of a web will not occur.
