Abstract:
1. A method of compensating for defects in printed images comprising: generating image data corresponding to a first printed image formed by a plurality of inkjets arranged in a cross-process direction in a printer; identifying a first defect in the first printed image with reference to the image data of the first printed image; identifying a candidate inkjet that generated the first defect with reference to a cross-process direction location of the first defect in the image data of the first printed image; modifying operation of the candidate inkjet to form a second printed image; generating image data corresponding to the second printed image; identifying that a second inkjet in the plurality of inkjets other than the candidate inkjet generated the first defect in response to a second cross-process direction location of a second defect identified in the image data of the second printed image being within a predetermined cross-process direction distance of the cross-process direction location of the first defect; operating the candidate inkjet in an original mode of operation in response to the second inkjet being identified; and modifying operation of the second inkjet in the cross-process direction to form a third printed image.
