  • Imageable elements and methods useful for providing waterless printing plates
    Patent number: 8283107
    Abstract: An imageable element can be imaged using non-ablative processes. This element has a non-silicone, non-crosslinked layer contiguous to and under an ink-repelling crosslinked silicone rubber layer. These elements can be used for providing lithographic printing plates useful for waterless printing (no fountain solution). Processing after imaging is relatively simple with either water or an aqueous solution consisting essentially of a surfactant or mechanical means to remove the crosslinked silicone rubber layer and a minor portion of the non-silicone, non-crosslinked layer in the imaged regions.
    Type: Grant
    Filed: June 5, 2008
    Date of Patent: October 9, 2012
    Assignee: Eastman Kodak Company
    Inventors: Ophira Melamed, Jianbing Huang, Efrat Konstantini
  • Imageable elements useful for waterless printing
    Patent number: 8026041
    Abstract: A non-ablative negative-working imageable element has first and second polymeric layers under a crosslinked silicone rubber layer. These elements can be used in a simple method to provide lithographic printing plates useful for waterless printing (no fountain solution). Processing after imaging is relatively simple using either water or an aqueous solution containing very little organic solvent to remove the imaged regions. The crosslinked silicone rubber layer is ink-repelling and only the first layer that is closest to the substrate contains an infrared radiation absorbing compound to provide thermal sensitivity.
