Abstract
Lithographic printing plates suitable for imaging by means of laser devices that emit in the near-infrared region. Laser output ablates a titanium layer sandwiched between an oleophobic or hydrophilic layer and a polyester layer, resulting in an imagewise pattern of features on the plate. The image features exhibit an affinity for ink or an ink-abhesive fluid that differs from that of unexposed areas.
