  • Patent number: 6691618
    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.

  • Patent number: 6523471
    Abstract: A process for imaging a lithographic printing plate having a coating containing diazo resins. An ink jet printer is used to apply micro drops of a basic chemical solution that insolubilizes the affected areas of the coating to a developing solution. The latent image may be cured by heating the plate for a short period, and is then developed. The process works with conventional, commercially available lithographic plates and developers.
