摘要
A method for estimating color measurements of color samples includes printing a color sample based on input data, measuring a color of the printed color sample with an in-line spectral sensor at a first temperature, and estimating a color of the printed color sample which would be output by a reference spectral sensor at a second temperature. The estimation is based on a thermochromatic model which represents relationships between measured colors of printed color samples on the in-line spectral sensor at the first temperature and the reference spectral sensor at the second temperature. The reference spectral sensor is a different type of sensor from the in-line spectral sensor, so the color response of the two spectral sensors is different, even when the measurement conditions are identical. Consequently, a set of printed spot color samples generate different measured colors at the second temperature on the in-line spectral sensor from the reference spectral sensor. The exemplary method allows these differences, as well as measurement temperature differences to be accounted for in the estimation.
