ABSTRACT OF THE DISCLOSURE Relative movement is effected between an original to be copied and an optical projection system. During such movement, the projection system projects the image of successive strip-shaped portions of the original onto successive strip-shaped portions of a recording medium, to form a gap-free reproduction of the original. The projection system includes a plurality of optical elements at least two of which are of positive refractive power and project an image of a strip-shaped portion of the original into an intermediate image plane and from there onto the recording medium. At least one of the optical elements of the projection system comprises an ele- ment having a lenticular layer of positive refractive power and a reflective layer combined therewith. -1-
