ABSTRACT:
A printing member for a press without dampening made by forming on a metal substrate an organic plastic layer having an exposed surface which is highly oleophobic and thermally decomposing the layer surface at selected image points thereon without contacting the surface and without penetrating through the layer so that there is a transformation of the surface structure which renders said surface oleophilic at said image points.
