Abstract
A method and apparatus for writing onto a photosensitive material with a single white light source. The apparatus includes a light source for producing a light composed of at least two color components, a collimating lens for collimating the light emanating from the light source so as to form a beam of light, and a beam splitter for splitting the beam of light into a plurality of individual predetermined beams of light, each having a different color. A modulator is also provided for modulating the intensity of each of the color beams of light individually in accordance with image data for each of the colors. The individual light beams are then recombined into a single beam of light and directed onto a photosensitive material.
