Title
(EN) PHOTOSENSITIVE PLANOGRAPHIC PRINTING PLATE AND FABRICATION PROCESS THEREOF
(FR) PLAQUE D'IMPRESSION PLANOGRAPHIQUE PHOTOSENSIBLE ET SON PROCEDE DE FABRICATION
Abstract
(EN)
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.
(FR)
Plaque d'impression planographique photosensible capable d'éviter les défauts de qualité, tels que les pellicules résiduelles, par exemple, et d'améliorer la productivité, ainsi que son procédé de fabrication. Ceci consiste d'abord à supprimer le revêtement d'une couche placée dans une zone correspondant à une partie périphérique de la plaque PS. Ceci permet d'éliminer le brouillard qui se produit sous l'effet de la pression au moment du découpage de la bande.
