Abstract
A method for calibrating one or more printheads includes printing a reference image using a first portion of image forming points of a first printhead, printing a diagnostic image using a second portion of image forming points of either the first printhead or a second printhead, detecting an optical density of the combined reference image and the diagnostic image and determining a compensation value based upon the optical density.
