Abstract:
1. An apparatus for printing an image from digital data onto a photosensitive medium, the apparatus comprising: (a) a control logic processor for accepting an image data input stream and providing image pixel data for a two-dimensional image; (b) a light emissive array for forming a two-dimensional exposure image according to said image pixel data, said light emissive array comprising a plurality of individual light-emitting elements arranged in multiple rows and columns, wherein each said light-emitting element corresponds to a pixel in said image pixel data, an intensity of each said light emitting element varying according to the digital data value for each said pixel; (c) imaging optics for directing said two-dimensional exposure image onto the photosensitive medium; and further comprising an actuator to offset the position of said light-emissive array relative to the position of said photosensitive medium for dithering.
