ABSTRACT A method is disclosed for the digital color correction of measured color picture values during color picture reproduction. A pattern is trichromatically sensed to create color measuring values which are trans- mitted to an input of a color correction calculator. The color correction calculator is adjusted to obtain desired corrected color values. A succession of signal values which are representative of the color space used during the reproduction process are applied to the color correction calculator to create a set of digitalized color corrected dosing values. This set of digitalized color corrected values is placed on a medium such as punched tape and then applied to a memory in the reproduction system. The corrected color dosing values are then utilized in reproducing a color picture.
