Claim One:
1. A method of determining multi-level printing parameters for a printing device, the method comprising; identifying a plurality of printing parameters for each of a plurality of colorant levels; providing at least one density measurement at a known coverage for each of the plurality of colorant levels; providing an aim curve relating input tone value to printed density value; identifying a plurality of test parameter sets, each test parameter set comprising a value for each of the plurality of printing parameters for each of the plurality of colorant levels; for each of the plurality of test parameter sets at each of a plurality of input tone values, determining a printed density value based on the printing 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; selecting a one of the plurality of 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 using the selected one of the plurality of test parameter sets and the plurality of colorant levels.
