Abstract
A process for making a lithographic printing plate, comprising: an exposure step of imagewise exposing a lithographic printing plate precursor that comprises, above a hydrophilic support, a photosensitive layer comprising (A) a compound that generates a radical upon the application of light or heat, (B) a polymer having an aromatic carboxy group in a side chain, (C) a polymerizable compound, and (D) an infrared absorber; and a development processing step using one type of processing liquid, wherein the processing liquid has a pH of 8.5 to 10.8.
