Abstract
In an apparatus for producing images on a light-sensitive material, the graphic information content for an image that is to be projected onto the light-sensitive material is divided into individual pixels. The projected image is composed of mutually offset partial images that are represented in a transmissive device consisting of an array of transmissive elements. The apparatus includes a light source that generates light rays passing through the transmissive device, an illumination device that bundles the light rays into light beams before they pass through the transmissive device, and a projection objective that projects the light beams telecentrically onto the light-sensitive material.
