Claim One:
1. In an imaging system, a method for spatial uniformity correction, the method comprising: determining an achievable gamut, wherein the achievable gamut is a gamut achievable by the imaging system for at least one of: all spatial locations of an output image, all print engines of a plurality of print engines, and at least one printer within a cluster of printers; determining a mean gamut, wherein the mean gamut is any gamut containing the achievable gamut; performing a gamut mapping from the mean gamut to the achievable gamut; determining a set of transformations for each of a set of input colors to a set of target colors, the set of target colors selected from colors in the achievable gamut; for a received digital image, transforming values of at least one of each received image pixel and clusters of received image pixels to transformed values based on the determined set of transformations; and generating an output image based on the transformed values.
