Abstract
A multi-color beam exposure system produces light of plural colors focused to form a multi-color focused image on the photosensitive material issued around a drum. The exposure system produces a plurality of light beams of each of the multi-colors and focuses each plurality of beams of the same color along the axial direction of the drum to thereby simultaneously scan the photosensitive material along a plurality of scanning lines. To reduce the size and weight of the drum scanner, the light sources producing the multi-color beams are placed remote from the drum and an optical fibers system transmits and focuses the multi-color beams onto the photosensitive material.
