Abstract :
Screen design requires that the stacking property be obeyed. This constraint limits the texture quality at each gray level. To improve the texture quality, we introduce a look-up-table based halftoning algorithm for which the stacking constraint is not necessarily satisfied but the binary patterns for individual levels are still correlated. The algorithm improves the halftone image quality compared with screening
