An elongate substrate such as a strip of paper, fabric, synthetic resin sheeting, or foil is imprinted with a plurality of images of different colors successively and in registration to achieve a composite multicolored image. The apparatus includes a plurality of independent image printing stations through which the substrate is passed. In one embodiment each image printing station includes one electrophotograhic sleeve. A latent image corresponding to one of the color images of the composite image is formed on the sleeve. The image so formed is toned, transferred to the substrate and then fixed thereto. In another embodiment each image printing station includes two electrophotographic sleeves. A latent image corresponding to one of the color images of the composite image is formed on one of the two sleeves. The image so formed is toned and then optically projected onto the second sleeve. The projected image on the second sleeve is toned, transferred to the substrate and then fixed thereto. |
