Abstract

An apparatus for optically projecting pixel-based image information onto a light-sensitive material has an image-generating device, an optical projection device, and a device for laterally offsetting the projected image of the image-generating device to produce a plurality of mutually offset partial images in the image plane. The offsetting device has two optical elements arranged in sequence in the light path of the projection. The projected partial images are offset relative to each other by tilting one or both of the optical elements.
