Abstract
A low toner pile height color image reproduction machine is disclosed for forming full-gamut toner images approximating a “look and feel” of offset lithographic images. The reproduction machine includes a single moveable endless image bearing member having a path of movement; at least a charging device mounted along the path of movement for uniformly charging a portion of the image bearing member; a controller including an image processor for converting digital image signals into at least seven bitmaps pixels of color separation images including black (K), cyan (C), red (R), magenta (M), blue (B), green (G) and yellow (Y); at least an exposure device mounted along the path of movement for imagewise exposing the portion of the single moving image bearing member to a light pattern of a first one of the at least seven bitmaps to form a first color separation latent image having first image areas and first background areas; and at least a development apparatus mounted along the path of movement for developing the first image areas of the first color separation latent image using toner particles having a color corresponding to that of the first one of the at least seven bitm…
