Abstract
A method and system compensates for malfunctioning inkjets using contone values for an image prior to the contone values being rendered for printing of the image. The method generates contone values for color space components in a compensation level for each malfunctioning inkjet. The contone values in each compensation level are modified with reference to a profile selected for each malfunctioning inkjet and with reference to the modification of the contone values in the vicinity of each malfunctioning with the compensative level. The modified contone values of each compensation level are merged with the contone values in the vicinity of each malfunctioning inkjet. The contone values are then rendered and used to operate inkjets for forming an ink image on an ink receiving member.
