Abstract
A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface with a rough surface morphology by an electroforming process which leaves the surface with a matte-like finish. Light reflected from the ground plane formed with the matte finish is diffused through the bulk of the photosensitive layer breaking up the interference fringe patterns which are otherwise later manifested as a plywood pattern on output prints made from the exposed sensitive medium.
