Claim One:
1. A method for correcting color registration errors while printing a print job on a print media using a color printer, the print job including image data for a plurality of document pages having pixel values specifying ink coverage for a plurality of color planes, comprising: receiving pixel values for a set of the document pages; analyzing the received pixels values for the set of document pages to determine a periodic pattern of ink coverage having a repeat period; using the color printer to print the image data for a first subset of the document pages using the color printer, wherein the first subset of the document pages includes at least one repeat period; measuring color registration errors for the printed first subset of document pages; analyzing the measured color registration errors to determine a periodic pattern of color registration errors; determining a repeating pattern of color registration correction values corresponding to the periodic pattern of color registration errors, wherein the color registration correction values specify image plane corrections for at least one of the color planes; and using the color printer to print the image data for a second subset of the document pages using the determined repeating pattern of color registration correction values.
