Abstract
A method for producing a printable lithographic plate from a negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. Steps include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and blanket exposing the developed plate with a source of energy which further reacts the retained unreacted material in the image areas. A plate with a coating containing resin particles can be imaged to produce initial cross-linking, then mechanically developed. Hardening of the imaged areas is completed with a relatively intense post-heating at 160 deg. C., which further cross links the monomer and fuses the resin particles.
