Abstract:
A calibration or characterization system is provided wherein the number of repeated patches or the size of a patch of a given color is printed to be approximately proportional to the square of the expected noise level. In that way, when multiple measurements for a given patch are averaged, all patch averages have approximately the same reliability.
