ABSTRACT:
A method for characterizing a color reproduction device. A first output color measure responding to a first reference input color value is measured under normal measurement conditions. The measurement conditions are modified and a second output color measure responding to the first reference input color value is measured under the modified measurement conditions. A transformation rule, enabling transformation between the second output color measure and the first output color measure, is calculated from the first color value and the second color value. A first set of output color measures responding to a set of input color values is measured under modified measurement conditions, and the first set of output color measures is converted, using the transformation rule, to a second set of output color measures. A system and a control device are also provided.
