ABSTRACT:
Overall print quality is improved via a method whereby an actual image is printed, a virtual image is defined based on image data, and the actual and virtual images are compared to identify a printhead error pattern which may be used to correct subsequent printing errors. This typically is accomplished via a system which employs an optical device which views an actual image to produce optical data, and a controller which derives a virtual image from image data provided to the printhead. The controller then compares the actual and virtual images to identify an error pattern, and modifies subsequent image data to compensate for perceived errors.
