High-quality pictorial color printing by ionographic pixel tone control technology and its application to electronic imaging systems

Ion flow printing technologies, one of which is ionography, have possibilities of pixel tone control. The conditions of pixel tone control have been studied, and high quality color printing has been achieved. Pixel tone is controlled by the time duration of ion projection. The relation between the time duration and the amount of deposited charge show quite good linearity. Electrostatic latent images are developed by liquid developer and color prints have been obtained by developing cyan, magenta, and yellow images. The application of the ion flow printing technology to high quality electronic imaging systems, color photography image filing system, and color facsimile, is discussed.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
