ABSTRACT:
A process and an apparatus for the preparation of color formula for the reproduction of the color of a master are described. In the process, during a measurement, the gloss component of the reflected light is already suppressed with polarizing filters, so that the calculation of the colorant concentrations may be carried out independently of the surface conditions of the master to be reproduced (glossy, semigloss, matte) with a set of optical data of the colorants that are independent of surface conditions.
