Method of selective edge softening and rendering for the suppression of halo
First Claim
1. A method for eliminating halo defects in a print image, comprising:
- receiving and storing print image data;
selectively dilating a copy of the stored print image data to create an area of selective dilation; and
,halftoning the area of selective dilation with a different halftone type than the halftone which is used by the system as applied to the rest of the image.

Abstract
Selective edge softening and selective edge dithering is introduced into an image representation to improve local control where halo problems are expected. Selective areas of dilation are isolated and separately dithered or halftoned, the result of which is then swapped back into or substituted for the stored original image. In this manner misregistration and color plane-to-plane interactions can be compensated for in plural image forming station architecture systems. The same technique is also valuable in monochrome systems as an aid to overcoming edge displacement and slow toner problems when the selective edge softening is selectively applied to edges which are in particular perpendicular to the fast scan direction.
