A method for controlling inking during the printing process, in particular during the production run, in a printing press, the printing press having an imaging device coupled to a computing device operative for collecting image color measurement data from the imaging device, and numerically processing the image data, and in which color measurement data are obtained from printed images produced on an continuous basis, these data being used for control or regulation to influence image inking if a predetermined image color tolerance is exceeded, the method which comprises the steps of collecting the image color measurement data, over time using the image color measurement data for computing a color trend estimate; evaluating the color trend estimate and performing a corrective control of the inking if the color trend estimate data indicate that image coloring will move outside the allowable image color tolerance.
