Abstract

Apparatus for imaging photographic negatives onto light-sensitive photoprint material includes a platform (3) for the print material; a digital image projection system (2) with an electronic image generation unit; and an integrated analog image projection system (1) with an light source and a negative holder. The image generator of the digital image projection system is disposed outside the light ray path of the analog image projection system. The projection systems are so constructed and arranged that the photoprint material on the platform (3) can receive images from both projection systems simultaneously or consecutively. When a change is made for the projection of images by one projection system to the other, the two light ray paths remain unchanged.
