Document registration using registration error model

摘要

A method for correcting color registration errors for a print job including one or more documents having a plurality of color planes. A color registration error model is used to predict 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. An image plane correction value is determined based on the predicted color registration error, and the document is printed using the determined image plane correction value.

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; andprinting the document using the determined image plane correction value.
