Patent ID: 8486614

Claim:
A method for exposing a photo material comprising a plurality of zones to be exposed with a digitally calculated image by means of an image setter, by movement of which a continuous relative motion is carried out between the photo material and the image setter, and the exposure of the individual zones takes place during said motion; wherein the image setter features in the ray progression of an exposing light ray or ray bundle an exit pupil with an aperture width that corresponds essentially to an entrance pupil of the zones, and that the image setter is continuously moved relative to the photo material across the surface of the same and that the exit pupil is changed in its position relative to the image setter in such a manner that the exit pupil remains essentially stationary in relation to the zone to be exposed during the continuous motion of the image setter relative to the photo material, at least for the duration of an exposure time; and wherein the image setter performs an imaging with exposition light rays that are essentially parallel in the exit pupil, are imaged at infinity and carry the image information.
