Abstract
A method of forming an imaging blanket for a printing apparatus comprises preparing a support structure (e.g., mold) for receipt of a polymer blanket compound, introducing the polymer blanket compound in liquid state over the support structure, curing the polymer blanket compound to produce an imaging blanket, releasing the imaging blanket from the support structure, and etching a surface of the imaging blanket to form a texture pattern therein, the surface forming an imaging surface of said imaging blanket. An imaging surface providing desirable dampening fluid retention is provided. Wet etch, dry etch or a combination of both may be used. The polymer may be a silicone compound, may include 3 percent by weight granular material.
