Method and system for compensating for thermochromaticity differences in inline spectrophotometers

An algorithmic method to compensate for thermochromaticity errors in insitu spectral color measurements of a color printing device comparing;

• mapping a difference between spectral measurements of a printed color generated by the color printing device measured at a first temperature and at a second temperature wherein the mapping comprises a referenceable characteristic of the color printing device;
• measuring a selected color corresponding to a color input signal representing a desired color at the second temperature, wherein the selected color is measured at the first temperature;
• converting the measured color to a corresponding color when the measured color changes to the second temperature;
• and, assessing if the color is different from an expected color intended by the color input signal.
