  • 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.

  • Patent number: 7883833
    Abstract: A method for providing a lithographic printing plate includes developing an exposed imageable element with an alkali silicate-containing developer composition having a pH of at least 12.0. The developer composition is regenerated by adding to it an alkali silicate-containing regenerator composition having a pH of at least 12.0. Conductivity of both the developer and regenerator compositions is suppressed from the presence of one or more conductivity reducing agents (such as glycerin). This conductivity suppression in the developer composition is greater than the suppression of the conductivity of the regenerator composition.
