Abstract
A method of calibrating a printing system. Data defining a color mapping that maps a first set of n-dimensional color Input points to a corresponding second set of n-dimensional color output points, the color mapping representing a measured behavior of the printing system, is obtained. A smoothed mapping function of color input points that satisfies a predetermined optimization condition based on a mapping error between the smoothed mapping function and the color mapping is determined. The mapping error is a function of individual errors between outputs of the smoothed mapping function as applied to respective color input points in the first set of color input points and corresponding color output points from the second set of color output points as mapped from the respective color input points by the color mapping. The smoothed mapping function is used to calibrate the printing system.
