ABSTRACT:
Apparatus and method for imaging a lithographic plate having a metal first layer and a second layer underlying the metal layer, the first and second layers exhibiting different affinities for fountain solution and/or ink. Selective removal of the first layer in an imagewise pattern reveals the second layer, resulting in direct production of image spots. The plate is ready for printing at the conclusion of the imaging process.
