PROBLEM TO BE SOLVED: To find and compensate for misaimed printing elements in an array or other sources of quality degradation. SOLUTION: Automatically, quality of that image is measured (72) and operation modified (83) for later printing based on degradation found. At least one quality influencing parameter is varied (64) and measured quality (65) is then correlated (81) with the variation to guide modification. Another form quantifies (82) departure (151, 18) from image regularity (159, 19) along the array, and applies (83) the value to derive (84) reduced element usage weights (15-17, 15'-17') for use along the array-best by following a formula to obtain the weights from the departures. This reduces banding by taking incorrectly aimed elements wholly or partially out of service.
