ABSTRACT:
Apparatus and method for transferring a color image from an original document to a film or to an output paper. The apparatus involves the formation of the component monochromatic images containing selected color component information in a monochromatic toner particle image configuration. The separate images of the toner configurations are exposed onto a photosensitive film to reconstruct the original document. The component images can be formed on a clear material or, preferably, on a transparent colored material, the colored material serving to eliminate the need for a filter for each of the color component exposures needed to reconstruct the original image. In a second embodiment, the component images can be formed on transparent regions of electrostatic photoconducting drum. A suitable light source placed in the middle of the drum, can expose a film on a platten near the surface. Again the transparent photoconducting material of the drum can have a color in each of a plurality of predetermined sections to eliminate the need for filters during reconstruction of an image from component monochromatic images.
