摘要： An apparatus for optically projecting pixel-based image information onto a light-sensitive material (12) has an image generator (1) for physically representing the image information in the form of monochrome partial images in different exposure colors. A projected image of the physical representation is produced by an optical projection device (4) which includes an offsetting device (7, 38, 39, 38a, 39a, 38c, 39c) for laterally offsetting the projected image in the image plane of the apparatus. The offsetting device is controlled by a controller means in a manner that is dependent on the exposure color of the monochrome partial image currently being produced by the image generator.

摘要： An image in the form of image dots produced by one or more pixel generators is projected onto a light-sensitive material with a certain amount of light power over a certain length of exposure time. Each pixel generator is driven by a voltage of periodically alternating polarity which alternates between half-periods of negative voltage and half-periods of positive voltage, with the negative voltage and the positive voltage being equal in absolute magnitude. The exposure time for each image dot is allocated equally to the respective half-periods of negative and positive voltage.
