Title: Color corrected printing system

Abstract: A color process in which color copies of an original document containing color information are reproduced. In this process, successive single color electrostatic latent images are recorded on an image bearing member. Each successive single color electrostatic image is developed with particles containing a predetermined colorant therein. These particles are transferred from the single color electrostatic latent images in a prescribed sequence. The sequence of transfer is such that the colorant of each successive layer of transferred particles corrects for the impurities contained in the colorant of the previously transferred layer of particles. The final color rendition of the copy is, thereby, color corrected so as to substantially approximate that of the original document.
