A method and apparatus for writing onto a photosensitive material (46) with a single light source (12). The apparatus includes a light source (12) for producing light composed of at least two color components, a collimating lens (18) for collimating the light emanating from the light source (12) so as to form a beam (20) of light, and a beam splitter (22) for splitting the beam (20) of light into a plurality of individual predetermined beams (24, 26, 28) of light, each having a different color. A modulator (30, 32, 34) is also provided for a respective one of the beams (24, 26, 28) for modulating the intensity thereof individually in accordance with image data for each of the colors. The individual light beams (24, 26, 28) are then recombined into a single beam (20') of light and directed onto a photosensitive material (46). <MATH> |
