Abstract
A method of printing a half tone image on an image forming apparatus using toner that is fused to a substrate is provided. The method includes generating a dot design that represents the half tone image, the dot design being made up of a plurality of dots; analyzing the dot design using an algorithm; matching the dot design to an equivalent alternate design that represents the half tone image, the matching being based on results of the analyzing, the equivalent alternate design being made up substantially entirely of a plurality of non-dot shapes; forming the half tone image on the substrate using the equivalent alternate design; and fusing the half tone image on the substrate with a fuser device.
