摘要： A direct write lithographic printing plate includes a base layer; a metal light absorbing layer provided over the base layer; and a melanophobic layer provided over the metal absorbing layer and selected to have a thickness which minimizes reflection of light from the metal layer so that light which passes through a selected portion of the melanophobic layer and into the metal light absorbing layer, is absorbed by such metal layer to provide a heat source which causes the removal, at the selected portion, of the melanophobic layer.
