Title: Ink jet printing system and method

Abstract: A ink jet printing system includes an ink jet head from which is dischargedto form an image on a recording medium, an ink jet apparatus provided witha conveyer means for conveying the recorded medium, and a casing forscanning the ink jet head in the main or horizontal scanning directionintersecting the conveying direction of the recording medium, and aprinter driver for creating image information to be output to the ink jetapparatus on the basis of density information. According to the presentinvention, the ink jet system comprises: an image information detectingsection for receiving first image information to detect whether the firstimage information is seriously damaged due to detrimental effects ofsatellite dots; and an image information changing section for changinginformation to be used, if it is detected that the first image informationis seriously damaged due to detrimental effects of satellite dots, fromthe first image information to second image information less influenced bythe satellite dots than the first image information.
