摘要

Lithographic printing members suitable for imaging by means of laser devices that preferably emit in the near-infrared region. Laser output ablates an absorbing (preferably titanium) layer (404) sandwiched between an oleophobic or hydrophilic layer (408) and a polyester layer (400), resulting in an imagewise pattern of features on the member. The image features exhibit an affinity for ink or an ink-abhesive fluid that differs from that of unexposed areas. The member may be laminated to a plastic or metal support; in the latter case, the metal may be chosen or processed to reflect imaging radiation.
