Abstract
A method of printing (10) to a photosensitive media contains the step of imaging light from a light source through an optics assembly to a polarization beamsplitter (80). The polarization beamsplitter (80) produces a first polarized state and a second polarized state. The first polarized state is directed to a first filter to a first spatial light modulator. The first spatial light modulator is addressed with a first color signal to modulate the first polarized beam which is reflected back through the polarization beamsplitter (80). A second polarized light is passed through a second filter to a second spatial light modulator. A second color signal causes said second spatial light modulator to reflect a second modulated light beam through the polarization beamsplitter (80). The first and second modulated light beam are focused through print lens (110) onto a photosensitive media.
