Abstract

A method for processing a digitized continuous tone image for reproducing the image by a printing device, including (a) inputting a tone value of an input pixel of the image; (b) applying a plurality of levelsplit curves to the tone value, thus obtaining a plurality of level values, wherein each specific levelsplit curve of the curves corresponds to a level defined by (i) a combination of a dot density and a dot area; or (ii) an overlap of a plurality of such combinations; (c) inputting the plurality of level values to an error diffuser for obtaining an output pixel value for reproducing the image; wherein a fraction of the output pixels to be filled by an overlap of levels depends on the level values and is independent of the error diffuser.
