System and method for inoperative inkjet compensation

摘要

A method for operating an imaging device identifies inoperative inkjets in an imaging device and modifies non-image data values in response to the identification of the inoperative inkjets. The method halftones image data for forming an image by generating halftoned image data with reference to modified non-image data values to compensate for identified inoperative inkjets. The method operates inkjets using the generated halftoned image data to form the image. The non-image data values modified in response to identified inoperative inkjets and later referenced while halftoning may include halftone threshold array, per-output raster column “RasterType” or TRC data values.

1. A method of operating an imaging device comprising:
identifying inoperative inkjets in the imaging device; modifying non-image data with reference to the identified inoperative inkjets; receiving continuous tone image data for forming an image with the imaging device; applying the modified non-image data to the received continuous tone image data to produce image data that compensates for the identified inoperative inkjets in the imaging device; and operating inkjets within the imaging device with reference to the image data that compensates for the identified inoperative inkjets.
