Color mixture composition controlling method for printing machine, involves obtaining optical actual values from light, and producing adjustment color mixture by deviations between actual values and optical desired values

摘要

The method involves obtaining optical actual values from light (7), where the light has a reciprocal effect with parts of a print image (9) produced on a printing substrate (6) by a printing machine with a color mixture (11). An adjustment color mixture (31) is produced by the deviations between the actual values and optical desired values, where the mixture (31) is mixed with the mixture (11), and changes the proportions of pigments, and color mixtures are made available from different color mixing devices (16, 24). An independent claim is also included for a color mixture composition controlling system comprising a color mixture mixing device.
