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 one or more documents having pixel values specifying ink coverage for a plurality of color planes, comprising: receiving a color registration error model that predicts a color registration error value for a document as a function of ink coverage characteristics for the document, wherein the color registration error model is a parametric model having one or more parameters; and for each document within the print job: determining the ink coverage characteristics for the document; using the color registration error model to determine a predicted color registration error for the document responsive to the determined ink coverage characteristics; determining an image plane correction value for at least one of the color planes of the document responsive to the predicted color registration error; and printing the document using the determined image plane correction value.
