SUPPORT FOR LITHOGRAPHIC PRINTING PLATE MATERIAL, MANUFACTURING METHOD OF LITHOGRAPHIC PRINTING PLATE MATERIAL, LITHOGRAPHIC PRINTING PLATE MATERIAL AND PRINTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a support for a lithographic printing plate material excellent in processability (conveyability and taking-up properties) with no deterioration of blocking properties and scratch resistance even when reclaimed resin is employed, the manufacturing method of a lithographic printing plate material employing the support, the lithographic printing plate material employing the support and the printing method excellent in printability (image quality and starting properties of printing) employing this lithographic printing plate material.

SOLUTION: This support for the lithographic printing plate material consists of reclaimed resin occupying 30-70 mass% of the support. In addition, knurling is applied to the support for the lithographic printing plate material having the thickness (the film thickness) of at least 220 μm.
