Abstract: The present invention presents method and apparatus for anti-aliasing elements in pages containing variable information, to be printed by a digital printer. Each page element is pre-rasterized to a resolution higher by a given factor than the output resolution, and the pixels that belong to non-printable areas are denoted ‘Background’. During the anti-aliasing (averaging) process, each new pixel gets an attribute value, dependent on the higher resolution pixels that contributed to the new pixel: Background—if all contributing pixels were denoted ‘Background’. Opaque—if all contributing pixels were denote ‘Non-Background’. Semi-Background—if the contributing pixels were partly ‘Background’ and partly ‘Non-Backgroun’.
