| Summary: | A method for correcting at least one uniformity error selected from the group consisting of a process direction uniformity error and a cross-process direction uniformity error in an image printing system that prints on an image bearing surface movable in a process direction. The method includes printing on a media a test pattern that includes a plurality of segmented regions extending in the direction of the at least one uniformity error being corrected, receiving a correction data from the user, and adjusting a profile of the image printing system to correct for the at least one uniformity error based on the received correction data Each segmented region comprising a coarse halftone area and a fine halftone area adjacent one another. The resolution of the fine halftone area is at least about 1.5 times the resolution of the coarse halftone area. |
