ABSTRACT:
A color scanner is provided having a commonly mounted and driven original scanning table and LED dot generator exposure source. Scanning is accomplished by illuminating a strip of the original artwork with high intensity fluorescent light and detecting the illuminated strip through a linear scanning aperture, lens and color filter wheel using a charge coupled device ("CCD") linear detector. Original artwork is held by vacuum against the flat original artwork receiving surface and photosensitive material is automatically loaded and held by vacuum onto the surface of a rotating exposure drum mounted parallel to the direction of travel of the LED dot generator exposure source, and the exposed halftone film is automatically removed from the drum surface and loaded into a transfer cartridge. Advantageously, multiple linear scans may be averaged in order to reduce color fringe effects. As a further advantage of the present invention photosensitive material is loaded and unloaded from the exposure drum in daylight operation.
