Abstract
Disclosed is a processor-implemented method for limiting ink output of marked image data using a target printer. A processor determines a constrained output (CMYK) LUT node data set for outputting the image data using the target printer to thereby mark the image data using a limited amount of ink. The constrained set is determined by re-encoding an encoded emulation output data, i.e., constraining an initial LUT node data set for the target printer based on a second. ICC profile with a smaller gamut. This allows the printer to inherit the smaller gamut. By constraining the initial LUT as disclosed herein, the final, constrained set emulates the smaller gamut in the target printer without suffering from pathological outcomes. The method enables the printer to inherit a natural ink limit methodology for the output colors that is more relatively proportional, and in a single destination profile.
