Abstract
A continuous-tone image, which can be in full color, is scanned to produce color-separation images in halftone dots. Edges of features in the scanned image are sensed, and the positions and shapes of the halftone dots that define corresponding edges in the halftone reproductions are adjusted so that they conform better to the feature edges. This reduces or eliminates the apparent serrations or roughness of feature edges in the halftone reproductions otherwise caused by misalignment of the halftone dots with the feature edges and improves image definition.
