Abstract: A printer includes first and second marking units for printing respective first and second image planes on a receiver medium. A digital image capture system is positioned downstream of the second marking unit, and is used to capture an image of printed first and second image plane. Image data for the first and second image planes is compared to the captured image of the respective image planes to determine respective first and second displacements between the nominal locations and the actual locations of the printed image data. Corresponding spatial adjustments are applied to image data for at least one image plane of a subsequent image to provide reduced alignment errors between the printed image data for the first and second image planes in the subsequent image.
