Abstract
Apparatus and method for producing color proofs electrophotographically. A platen carrying an electrophotographic member is translated sequentially past functional stations including a charging station, an exposure station, a toning station, a transfer station and a cleaning station. Once toning is completed, the platen carrying the toner image is translated to the transfer station. An intermediate transfer medium is disposed at the transfer station as the sole receptor of the toner image from the electrophotographic member. A roller effects transfer engagement between the intermediate transfer medium and the toner image carrier. Direct transfer mode or offset transfer mode electively is provided at the transfer station. For offset mode, the toner image on the photoconductive layer involves first transfer to the intermediate transfer medium and from the latter to the transfer medium. The direct transfer mode is effected by employing, as an intermediate transfer medium, the same material as the transfer medium. Successive color separation transparencies are substituted in sequence respectively to form the finished color proof.
