Abstract
A method and apparatus for printing stroke and contone data together are provided in which data to be printed (102) is identified by a processor (100) as being either stroke or contone data. For contone data, processor (100) controls a light source (14), a spatial light modulator (12), and an optical photoconductive drum (16) to generate image quality graphics by using spatial light modulation in the process and cross-process directions. For stroke data, processor (100) controls light source (14), spatial light modulator (12), and optical photoconductive drum (16) for high resolution printing by using intensity modulation. Processor (100) is operable to control light intensities through the use of lookup tables stored in a memory (104).
