Abstract
An apparatus for correcting color images in an electrophotographic printing machine in which a first image is developed on a photoconductive surface, the second and subsequent images are superimposed over the first developed image. The apparatus includes an input device for inputting an image signal having a plurality of color components. An image processing unit processes the inputted signal. The image processing unit includes an adaptive exposure processor that modulates the exposure level of a raster output scanner (ROS) for a given pixel as a function of toner previously developed at the pixel site, thereby allowing toner layers to be made independent of each other.
