<p>A method of making an imaged printing plate, comprising the steps of directing laser energy through a transparent substrate having thereon a coating comprising particles which absorb said laser energy, a self-oxidizing binder and a cross-linking agent or a cross-linking agent in combination with a cross-linkable resin or a non-oxidizing polymeric material or resin, said coating being in intimate contact with a lithographic printing surface, thereby causing the coating to be selectively transferred from the film to the surface. Material is transferred by the laser beam from the transparent carrier film to a lithographic surface, thereby producing a planographic printing plate and a film having clear areas corresponding to the image on the plate.</p> |
