More Information
Summary:A system and method enable determining a total colorant limit for printing images. The system includes memory which stores instructions for: determining a grain value for each of a set of printed patches printed on a first print media, the grain value being based upon a visual contrast sensitivity function computed for the respective patch, the set of printed patches including patches printed on the print media at different total colorant values; determining a total colorant limit for the first print media, as a function of the total colorant values and corresponding grain values for the printed patches in the set, wherein the total colorant limit is a total colorant value which corresponds to a grain value which does not exceed a threshold grain value for the first print media. A processor executes the instructions.
