ABSTRACT:
A method for reducing the occurrence of print artifacts in an imaging machine includes the steps of applying an electronic printhead skew correction to image data corresponding to at least one of a plurality of image planes, e.g., of a cyan image plane, a magenta image plane, a yellow image plane and a black image plane, to generate skew corrected image data. Thereafter the associated halftone screens are modified to eliminated halftone noise introduced by the electronic printhead skew correction. If text characters are present, block boundaries are effectively shifted to reside in the spaces between adjacent text characters.
