Figure 1: (a) Digital halftone and high resolution scan of printed output at: (b) 300 dpi (c) 600 dpi. We have shown that a measurement- based printer model based on data collected from a high resolution scanner coupled with DBS yields images that have richer gray regions, very high spatial res- olution and visually pleasing textures. Since the measurement model reflects the actual dot-interactions, it has the ability to bet- ter exploit the intermediate gray levels caused by dot overlap than other models. We have also shown that the algorithm can be ef- ficiently implemented by recursively evaluating the effect of trial changes. Figure 3: Bullseye halftoned by clustered dot screen.
