Abstract
A method of determining multi-level printing parameters for a printing device includes identifying printing parameters for each of multiple colorant levels; providing at least one density measurement at a known coverage for each colorant level; providing an aim curve relating input tone value to printed density value; and identifying multiple test parameter sets. The method further includes, for each of the test parameter sets at each of multiple input tone values, determining a printed density value based on the parameters of the test parameter set and the density measurements, and determining an error value from differences between the determined printed density values and the aim curve. The method also includes selecting one of the test parameter sets using the determined error values; and communicating the selected one of the plurality of test parameter sets for receipt by the printing device for printing documents. Systems and software can employ the method.
