Abstract:
A process for making a lithographic printing plate is provided that includes (A) a step of preparing a lithographic printing plate precursor that includes above a support a photosensitive layer that includes (i) a binder polymer, (ii) an ethylenically unsaturated compound, and (iii) a radical polymerization initiator, (B) an exposure step of exposing the lithographic printing plate precursor, and (C) a development step of removing the photosensitive layer of a non-exposed area of the lithographic printing plate precursor, the development step (C) being carried out by means of a developer that includes an enzyme. There are also provided a developer for a lithographic printing plate precursor, the developer including (a) an enzyme and (b) a surfactant, and a replenisher for lithographic printing plate precursor development, the replenisher including an enzyme.
