  • Patent number: 6613496
    Abstract: A method for forming a dampening-waterless lithographic plate comprising an irradiation step of irradiating a dampening-waterless lithographic blank plate imagewise with a laser beam, the blank plate comprising a support, a photothermal conversion layer provided on the support for converting laser beam energy to heat, and an ink-repellent layer provided on the photothermal conversion layer a first rubbing step of rubbing the surface of the ink-repellent layer without use of a liquid so as to remove at least a portion of the ink-repellent layer in areas irradiated with a laser beam and a second rubbing step of rubbing the surface of the partially removed ink-repellent layer through use of a liquid.

  • Patent number: 6083664
    Abstract: A method for producing a planographic printing plate comprising the steps of: producing an original planographic printing plate which comprises a substrate, and a first layer and an ink-repellent layer having an ink-repellent surface in that order on said substrate, wherein the first layer converts laser light to heat and enables peeling of upper layers disposed on said first layer; exposing said original planographic printing plate by laser light; and rubbing the surface of said original planographic printing plate, which is the surface of said ink-repellent layer, with a rubbing member in the presence of an aqueous solution containing a nonionic surfactant to physically remove laser-exposed portions of said ink-repellent layer, thereby forming the planographic plate, is provided.
