A contone reproduction method and apparatus for converting an input set I(x,y,c) of contone signals to an output set B(x,y,d) of binary signals suitable for driving a selected output device, utilizing a screen cell defined by repetitions of a subcell based on a subcell matrix (100) of threshold factors to which an offset is applied (102) in accordance with the position of the repetition of the subcell in the screen cell to obtain threshold signals, and wherein the particular subcell matrix of thresholds is selected in accordance with the determined image characteristic. <IMAGE> |
