Abstract:
An image printing system in which a light source is modulated in accordance with an image bit stream in order to represent an image in charges on a printing drum, the system comprising:said image bit stream; and a processor for processing said image bit stream; wherein; said processor identifies segments of said image bit stream representing substantially solid horizontal lines or edges; said processor modifies said segments of said image bit stream representing a substantially solid horizontal line or edge, said processor modifying said identified segments of said image bit stream so as to decrease an amount of toner resulting in those portions of a printed image corresponding to said identified segments of said image bit stream; and wherein said processor modifies said segments of said image bit stream representing a substantially solid horizontal line or edge such that said segments of said bit stream as modified represent an outlined area containing a fill pattern that replaces said substantially solid horizontal line or edge.
