摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated body of a lithographic printing plate material which enables a lithographic printing plate material having a good damage prevention property for the image forming layer due to aluminum powder and excellence in laminating property, printing quality, and printing resistance.;SOLUTION: The method for manufacturing the laminated body of a lithographic printing plate material includes: the manufacturing process where the lithographic printing plate material is manufactured by applying an image forming liquid onto the long aluminum support body and drying to form the image forming layer; the cutting process for cutting the lithographic printing plate material; the conveying process where the cut lithographic printing plate material is conveyed using conveying delivery rolls; and the laminating process for laminating the conveying lithographic printing plate material. The surface of at least one of the conveying rolls characteristically has a recessed part of 0.10 mm or more in depth.;COPYRIGHT: (C)2009,JPO&INPIT
