A post-processing edge enhancement technique that is applicable to all half-toning algorithms is proposed. Two types of edge pixels, dark and light edge pixels, are identified. Edges in an image are highlighted by setting the dark/light edge pixels to black/white. The method is tested on a laser printed and the evaluation technique is restricted to clustered half-toning methods.
