A system for exposing a material with images includes an exposure table and an electronic light projector arranged above the exposure table. The system is adapted to project images towards a material arranged at the exposure table. The electronic light projector and the exposure table are configured to be moved relative to each other during exposure. The electronic light projector is connected to a projector control unit configured to provide a sequence of images to be exposed represented by image data and superimpose a static image pattern onto the edge sections of the images to be exposed, resulting in a sequence of combined images. The width of the static image pattern is slimmer than the image to be exposed. The electronic light projector is configured to expose the combined images sequentially onto the material.
