Claim One:
1. A system for calibrating a digital color imaging device, the system comprising: a color output device for printing an image file including a test pattern, the test pattern comprising a plurality of strips, each strip comprising a plurality of test patches, the test patches for each strip comprising scales of percentages of a fixed number of at least two C, M, Y, and K colorants; a measurement device that measures each of the test patches for colorimetric data; a processor for calculating the total colorant limit by: receiving the colorimetric data from the measurement device based upon the colorimetric data; selecting one patch in each strip with a minimum lightness; determining, for each patch in each strip that was selected by the processor as having a minimum lightness, a total area coverage (TAC), the TAC comprising a sum of the percentages of colorants used to produce the patch; selecting a maximum TAC from the TAC determined for each patch in each strip that was selected by the processor as having the minimum lightness; and the processor setting the total colorant limit to the maximum TAC selected by the processor.
