Dot diffusion, associated with Donald Knuth's work, processes the image in blocks rather than in a single scan, which produces a mezzotint-like, clustered-dot texture. The result can look more like traditional print halftoning than standard error diffusion, so it suits artistic and print-style engravings where you want a visible, deliberate pattern. It is a good choice when you are after a distinctive look rather than maximum photo realism.
