Abstract
A method and system are provided for characterizing performance of a printer across a plurality of halftone screens. A first non-uniformity profile is generated by measuring printer performance. Cross-position differences between the first non-uniformity profile and selected corresponding cross-positions of a second halftone screen are detected. A scaling factor is computed relating the detected differences. Printer performance with the second halftone screen is predicted by applying the scaling factor associated with the second halftone screen to the non-uniformity profile of the first halftone screen.
