Paper Abstract

This paper describes the Coulter Systems Corporation Laser Color Recorder, which records three color - Red, Green, Blue (RGB) - continuous tone images of up to 8196 by 10240 pels, up to 12 bits deep per color, on most color films and papers. This recorder produces images in formats from 35 millimeter half-frame to 12 by 18-inch. Half resolution, up to 4096 by 5120 pels is also available. All image formats have the same available resolutions except for differences due to aspect ratio. The basic writing engine will produce an image in less than five minutes, in any format and resolution. Additional digital processing modules will be available to provide a wide variety of interfaces, real time scaling for resolution adjustment, color coordinate conversion (e. g. CMYK to RGB), and "printing type" halftone screening.
