Claim One:
1. A system for calibrating a digital color imaging device to a printing press, the digital color imaging device comprising first and second colorants, the first colorant comprising a first shade of a color, the second colorant comprising a second shade of the color different from the first shade, the printing press comprising a color profile, the system comprising: an image source comprising a test pattern adapted for printing by the color output device; an instrument adapted to calorimetrically measure the printed test pattern; and a processor adapted to: (a) receive colorimetric measurements from the instrument and calculate therefrom a tonal response for the digital color imaging device; (b) receive a colorimetric value from the color profile and calculate therefrom a tonal response for the printing press; (c) receive a first range of input values and a second range of input values; (d) receive an amount of the first colorant at an end of the second range of input values; (e) map the tonal response of the first colorant to the tonal response of the press for the first range of input values; (f) calculate a tonal response of the first colorant for the second range of input values; and (g) calculate the tonal response of the second colorant for the second range off input values based on the tonal response of the printing press and the calculated tonal response of the first colorant for the second range of input values.
