PLATEMAKING METHOD OF LITHOGRAPHIC PRINTING PLATE PRECURSOR

摘要

PROBLEM TO BE SOLVED: To provide a platemaking method of lithographic printing plate precursor which is excellent in printing durability, produces no stain on a printed matter from the beginning of the printing and can reduce waste sheet drastically.

SOLUTION: The platemaking method of lithographic printing plate precursor includes: a process of forming an image by using a printer of inkjet method on an image reception layer of a lithographic printing plate precursor having the image reception layer mainly containing inorganic fine particles on a water resistant support; and a process of subsequently desensitizing the image reception layer by using a desensitizing solution containing at least nonionic surfactant.
