Abstract
A method of printing an image utilizing a printer having print nonuniformities, the method comprising the steps of converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information comprises defining each pixel as either a background pixel, interior pixel, or an edge pixel; and, reassigning the digital value of one or more edge pixels or interior pixels to lower values independently in order to reduce toner consumption. The rendering of the present invention occurs post RIP.
