Patent ID: 8547592

Claim:
A device for the digital exposure of light-sensitive materials, with an electronic picture memory for storing a master image, with an exposure unit which comprises a light source, an electronically activatable spatial light modulator for representing a two-dimensional part picture of the master image, and imaging optics for projection of the two-dimensional part picture onto the light-sensitive material, with a drive device comprising motors and a motor control, for the movement of the exposure unit parallel to the surface of the light-sensitive material, with a scroll means for scrolling a picture strip of the master image through the light modulator, and with a control device for synchronizing the drive device with the scroll means, wherein a rapid intermediate memory for storing a strip-like region of the master image is provided, from which the picture data for the two-dimensional part picture to be exposed in each case, is transmitted onto the light modulator synchronously with the movement of the exposure unit.
