Abstract

Abstract A variety of sizes of color prints are made electrophotographically utilizing a single large size receiving sheet, for example, a receiving sheet that is 12×18 inches. The large size receiving sheet can be secured to a transfer roller to be cycled through the repeated single color transfers. The receiving sheet is large enough to receive one multicolor image of the largest size or an array of smaller sized multicolor images. The receiving sheet with smaller images is cut to size after transfer.
