Abstract
A method for characterizing a colour rendering reprographic apparatus for making an output colour profile comprises the steps of measuring a set of colour values, indicative of output of the colour rendering reprographic apparatus on a predetermined medium and processing these measurement data to profile data that are applicable for creating an output colour profile according to the standards of the International Colour Consortium. The processing step comprises a correction of a measured colour value with a medium compensation value that depends on the medium gray colour value at the same lightness as the measured colour value. The medium gray colour value is a value that results from the application of black colorant on the predetermined medium. The medium compensation value reduces to zero at the lightness of the predetermined medium. The effect of this processing step is that a profile is generated that gives prints that are both free of background colorant and have natural colour rendering.
