Modifying print data using matching pixel patterns

A method for aligning digital image data for a digital printer including at least one printhead, comprising:

• receiving one or more spatial adjustment parameters;
• receiving digital image data including image pixels having pixel values;
• modifying the digital image data to be printed with at least one printhead in accordance with the spatial adjustment parameters, wherein the modification of the digital image data includes:
• designating an input pixel neighborhood within which an image pixel should be inserted or deleted based on the corresponding determined spatial adjustment parameters;
• comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns and identifying a matching pixel pattern;
• and
• determining a modified pixel neighborhood having either one more image pixel or one less image pixel than the input pixel neighborhood, wherein the pixel values of the image pixels in the modified pixel neighborhood are determined responsive to the matching pixel pattern;
• and
• printing the modified digital image data using the digital printer;
• wherein the modification of the digital image data provides improved alignment of the printed image data with respect to a reference position.
