In this paper we propose an automated solution that compensates for CMYK inkjet printer output non-uniformities. The solution is applied to a printer employing fixed printhead arrays. The algorithm initially pre-processes scanned image of printed output to isolate the desired region of interest. The region of interest information is utilized to extract non-uniformities across the entire printed area. Finally, the algorithm concludes in a calibration step that enables compensation of the identified non-uniformities and provides the desired tonal target response.
