Abstract
A method and a printing system for gray balance correction of a printing process include determining first color values at on a gray axis of a color space of a reference printing process. These first color values determine tonal values describing a corrected gray balance of the target printing process. To avoid wastage and a further proof for gray balance calibration of the printing process, second color values of the printing process, describing the corrected gray balance, are derived from the first color values. The tonal values of the target printing process corresponding to the second color values are determined from first characterization data and the second color values of the printing process. A correction function created from these tonal values describes the corrected gray balance. Determining corrected characterization data is also possible. A printing form is produced and a printing material is imaged by using the corrected gray balance.
