Abstract
A method for gray scale printing combining row integration and pulse width modulation. A spatial light modulator (102) has one line (104) designated to perform PWM within a given line time. Another area of the modulator (106) has lines designated to perform row integration on the print image, allowing for more gray levels. An additional area (108) can be designated to correct for defects in the illumination profile and the printed images.
