1. Method of producing an imaging surface for an imaging system, comprising:
- providing a metallic substrate;
coating said metallic substrate with an elastomer layer having a chemically-reactive filler or base mixed therewith, thereby obtaining a coating on said metallic substrate;
etching said coating with an effective concentration of an acid reactive with the filler or base exposed at the surface of the coating, thereby providing reaction products including water-soluble salt at the surface of the coating; and
removing said reaction products by washing the coating surface with an aqueous liquid, thereby producing a plurality of pits at the surface of the coating.

Abstract
This is structure and method for providing a textured surfaced that can be used in a plurality of systems including ink jet printing. In ink jet printing, the textured surface of this invention controls ink drawback and significantly improves image quality. The textured surface has an average roughness, Ra, of about 0.2 to 1.5 microns, a texture density of about 104-107 pits per cm2, a texture size of about 0.5-5 microns, and a texture depth of about 0.5-10 microns.

10. Method of producing an imaging surface for an imaging system, comprising:
-
providing a metallic substrate or elastomer layered substrate with a relatively smooth surface, coating such substrate with a photoresist layer, Interposing a UV mask between a UV source and said photoresist layer, said mask having a plurality of openings of a predetermined size range, said mask comprising a material impervious to UV rays, said UV rays passing through said mask openings, exposing said mask to UV rays, thereby causing said UV rays to pass through said mask openings and thereafter causing portions of the photoresist layer to break down, removing those portions of the photoresist layer that were broken down by said UV rays, etching the resulting surface of such substrate to provide thereby a plurality of pits at the surface thereof, removing the remainder of the photoresist layer to provide thereby the surface of such substrate with said plurality of pits. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
