Abstract

The proprietary product of Coulter Information Systems, designated KC-Film, will be described in terms of physical makeup, operating characteristics and areas of application. KC-Film is a crystalline, transparent photoconductor made up of semiconductors so tiny that the layer contains 100 million to the square millimeter. The surface voltages utilized with KC-Film are very much lower than normally found in electrophotographic recording work. This results in the ability to produce extended grey scale continuous tone imagery without edge effects. KC-Film has sensitivity comparable to high resolution silver halide films and has spectral sensitivity throughout the visible region. The application possibilities demonstrated to this time include high resolution continuous tone imagery, offset, printing, high speed contact printing, microfilming, plain paper copying, and multi-megacycle laser recording. Presently available coating capability allows production of films up to 32 inches wide by 4000 feet long.
