ABSTRACT:
A method for color accenting selected portions of a photocopy wherein a photoconductive surface is exposed to a light image of the document being reproduced, the non-selected portions of the resulting latent image are erased prior to developing the image with a given colored toner, and the developed image is transferred to a copy sheet before a subsequent reproduction of the document is performed. During the subsequent reproduction, the non-selected portions of the latent image remain on the photoconductive surface and the selected portions are erased prior to development with a different color than the given colored toner of the non-selected portions of the document and the transfer of the non-selected portions to the same copy sheet that previously received the selected portions.
