An electrophotographic method of producing positive color proof copies from negative films wherein a charged photoconductor is exposed to the negative film and toned with a conductive toner forming image deposits in the unexposed areas. The conductive deposits are transferred to a dielectric paper and affixed thereto. The dielectric paper is charged, the charge being accepted only in areas free of the conductive deposits, i.e. the final image areas. The charged areas are toned with color toners and the color toner deposit transferred to printing stock to provide the positive proof. |
