Abstract
A method for correcting color registration errors for a color printer that prints color image data on a continuous web of media. A color registration error model is used to predict a color registration error value for a particular in-track position as a function of ink coverage characteristics for an image region including the particular in-track position, 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 color image data for the particular in-track position is printed using the determined image data correction values.
