Zusammenfassung:A method which corrects for malfunctioning or inoperable ink ejection elements (82) in a one-pass printmode. The method includes obtaining (140) a standard printmask; identifying (142) the ink ejection elements (82) which are malfunctioning; ascertaining (144) ink ejection elements (82) adjacent to the ejection elements which are malfunctioning; selecting (146) particular adjacent ink ejection elements (82) from the adjacent ink ejection elements (82); and modifying (148) the standard printmask by adjusting the amount of ink deposited by the selected adjacent ink ejection elements (82) to create a modified printmask.
