Abstract

A method of eliminating the effects of aliasing when printing objects having opposing edges. A center line between the opposing edges is identified. (FIG. 3). "Opposing pixels" on the edges are also identified and assigned offsetting grayscale values. (FIG. 4). This prevents the distances between the edges from appearing too narrow or too wide.
