Abstract
Disclosed is a system and method for gradually adjusting a look-up table (LUT) for a print engine in order to improve the regulation of color quality of printed images. The LUT is updated so that a target value for a particular color is achieved. This corrects for a measured or predicted change in a tone reproduction curve. Depending upon the severity of the required adjustment, a series of incremental adjustments rather than a single adjustment can be made to the LUT table over a period of time. Each adjustment in the series can be limited to a predetermined maximum delta so that any corrections made to the LUT following the generation and evaluation of one test image and before the generation and evaluation of the next test image for the same target color are gradually and imperceptibly implemented (i.e., unnoticeable).
