Patent number: 7829260Abstract: A method of treating a laser exposed lithographic printing plate with a deactivating solution followed by overall irradiation is described. The plate comprises on a substrate a photosensitive layer capable of photo hardening. The deactivating solution is capable of deactivating the photo hardening capability of the photosensitive layer in the non-hardened areas so that the overall irradiation does not cause hardening of the photosensitive layer in the non-hardened areas. The deactivation and overall irradiation cause one or more chemical or physical changes to the photosensitive layer, such as further hardening of the imaged areas, improved contrast, improved developability, or improved substrate hydrophilicity. The overall irradiated plate is further developed on press with ink and/or fountain solution or off press with a developer. For off-press development, the developer may be used as the deactivating solution.Type: GrantFiled: December 31, 2007Date of Patent: November 9, 2010Inventor: Gary Ganghui Teng

Patent number: 6145565Abstract: A metal substrate is treated with a plurality of rotating brushes and a slurry of particulate material such that the treated surface is capable of absorbing incident infrared laser radiation. The substrate is itself capable of being visibly imaged by selective writing with an infrared laser. The substrate is coated with an ablatable coating which is transparent to the imaging infrared laser radiation. Selective exposure to infrared laser radiation ablates this coating in the laser exposed areas as a result of the absorption of infrared radiation by the substrate. The substrate can be anodized after rotary brush graining and still retain its ability to be imaged and ablate a coating. The coated article can be imaged in a computer-to-plate infrared laser imaging device. Depending on the specific coating and substrate selection, the imaged article can be used in a conventional lithographic printing process or in a dryographic printing process.Type: GrantFiled: May 15, 1998Date of Patent: November 14, 2000Inventors: Howard A.
