<p>A method of calculating compensation data for compensating for spatial print engine non-uniformity of an image applied by a print engine to a receiver. A test target has two test areas of different output densities, each with a single output pixel level. A relationship between output density and output pixel level for the print engine is determined, and is used to calculate the output pixel level for each test area from the respective output density. The test target is printed, and the reproduced densities of the test areas are measured at a plurality of different locations in each area. A processor is used to calculate the compensation data using the measured densities. The compensation data defines a relationship between an output pixel location on the receiver, an output pixel level, and a compensated pixel level.</p> |
