Zusammenfassung:	An apparatus for printing images including an illumination optics (75) that provides uniform area light is disclosed. A polarizing beamsplitter (80) receives the uniform area light and redirects a first polarization state of the light to a first reflective LCD modulator (90) which modulates the first polarized light on a site by site basis and reflects the first modulator light through the polarizing beamsplitter (80). A parallel plate tilted at a first angle spatially displaces the first modulated light along a first line normal to the polarizing beamsplitter (80). A print lens assembly (110) images the first modulated light to a first position on a media plane to print a first image. The parallel plate is moved to a second position (250) and a new image is printed.
