Abstract
A color correction system for a color copier is enabled by means of a low resolution RIS unit attached to a light/lens scan system which creates an electronic raster image simultaneously with formation of a color latent image. The RIS output signals are used to modulate the output of a ROS unit which exposes the color latent image to a modulated color correction pattern. Color developer units are enabled to successively develop each color.
