ABSTRACT:
This application discloses a method of making high quality color prints by electrophotography. The prints are particularly suited to color proofing. A single photoconductive drum is used together with means to electrostatically charge, laser-scan expose, and toner develop during one rotation. In successive rotations different colored images corresponding to color separation images are assembled in register on the drum. This assembled color image is transferred to a receptor sheet in a final rotation of the drum.
