Abstract

A method of correcting for malfunctioning ink ejection elements in a printing system comprising the step of (a) obtaining a standard printmask; (b) assigning to at least two ink ejection elements a probability that each of such at least two ink ejection element will work properly; (d) attempting to modify the standard printmask by replacing ink ejection elements having a certain probability to work properly with different ink ejection elements having a bigger probability to work properly, to create a modified printmask.
