    摘要： Apparatus and method for exposing a lithographic printing plate wherein the apparatus includes a plurality of laser diodes emitting light of wavelength between 350 nm and 450 nm. The light from each of the laser diodes is directed onto the lithographic printing plate such that each spot on the lithographic printing plate receives light emitted from at least one of the laser diodes. Preferably, the lithographic printing plate is a violet-sensitive lithographic member and the lithographic member is a printing press plate. The power of each laser diode may be between 5 mW and 30 mW, and preferably the laser diodes emit light of wavelength between 390 nm and 430 nm.

    摘要： A waterless or driographic printing plate which can be thermally imaged by an infrared laser is composed of a substrate; a thermal imaging layer containing a photothermal conversion material, such as an infrared absorbing material, and a thermoplastic polyurethane with pendent allyl groups; and a crosslinked silicone polymer top layer. It was discovered that when the imaging layer contains an allyl functional polyurethane mixed with an infrared absorbing dye or pigment, the polymeric layer will have enhanced solubility in certain solvents when exposed to infrared radiation. In addition, the polymeric layer continues to exhibit excellent adhesion to the silicone in unexposed areas so that the infrared absorbing layer can endure development with a suitable organic solvent, or a solvent mixture. Mild brushing or rubbing with the developing solvent readily removes laser-struck portions of the infrared imaging layer while unexposed areas remain firmly intact.
