Abstract

A process for imaging a lithographic printing plate having a presensitizing coating. An ink jet printer is used to apply imagewise micro drops of an insolubilizing solution that insolubilizes exposed areas of the coating. The latent image is then developed. The process works with conventional, commercially available developing processors.
