Abstract
A method and apparatus for printing multiple simultaneous images onto a photosensitive media comprises the steps of imaging light from a light source through an optics assembly (75) to a polarization beamsplitter (80). The polarization beamsplitter (80) produces light having a first polarized state and light having a second polarized state. The first polarized light is directed to a first spatial light modulator (90). The first spatial light modulator is addressed with a first signal to create a first modulated light beam, which is imaged through a print lens assembly onto the photosensitive media. A second polarized light is directed to a second spatial light modulator (95). The second spatial light modulator is addressed with a second signal to create a second modulated light beam, which is imaged through the print lens onto the photosensitive media. The first modulated light beam and the second modulated light beam create at least two simultaneous images on the photosensitive media.
