Abstract
A method for increasing resolution in a image printed by an ink jet printer is provided. The method selectively removes painted pixels from a bit map to ensure that no two adjacent pixels are painted by the same ink jet. The method removes painted pixels in a manner that preserves the edges of characters and other features. The resulting processed bit map ensures that an individual print head jet always addresses at least one non-painted/blank pixel after each painted pixel it fills. This allows the speed of the receiving surface relative to the print head to be increased to thereby allow for greater resolution in the printed image for a given print time.
