Abstract
A method for aligning multi-channel digital image data for a digital printer having a plurality of printheads is described. A test pattern including test pattern indicia printed using individual printheads is scanned and analyzed to detect locations of the printed test pattern indicia. One of the printheads is designated to be a reference printhead, and one or more of the other printheads are designated to be non-reference printheads. Spatial adjustment parameters are determined for each of the non-reference printheads responsive to the detected test pattern indicia locations. Digital image data for the non-reference printheads is modified by designating an input pixel neighborhood within which an image pixel should be inserted or deleted, comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns to identify a matching pixel pattern; and determining a modified pixel neighborhood responsive to the matching pixel pattern.
