Apparatus and method for projecting graphic information onto a light-sensitive material
First Claim
1. An apparatus for producing projected images in different size formats on a light sensitive material, wherein the projected image represents graphic information that is divided into individual pixels, and wherein further the image is projected in the form of partial images that are laterally offset relative to each other, said apparatus comprising:
- a transmissive device for producing said partial images, a light source for generating light rays that pass through the transmissive device, an illumination device for guiding the light rays along a plurality of mutually parallel light paths through the transmissive device, and a projection objective for projecting the light rays representing the partial images onto the light-sensitive material, wherein the illumination device bundles the light rays into light beams before they pass through the transmissive device, and the projection objective projects onto the light-sensitive material only those light rays that run at least approximately parallel to the optical axis of the projection objective wherein there is substantially no overlap between adjacent partial images on the light sensitive material.

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.

13. A method for producing projected images in different size formats on a light sensitive material, wherein the projected image represents graphic information that is divided into individual pixels, and wherein further the image is projected in the form of partial images that are laterally offset relative to each other, said method comprising the steps of:
-
producing the partial images by means of a transmissive device, generating light rays, guiding the light rays along a plurality of mutually parallel light paths through the transmissive device, wherein the light rays are bundled into light beams before passing through the transmissive device and telecentrically projecting the light rays carrying the partial images onto the light-sensitive material with substantially no overlap between adjacent partial images on the light sensitive material after all of said partial images have been projected onto the light sensitive material. - View Dependent Claims (14, 15)
