Abstract

A method and an apparatus for compensating for inking differences between setpoint color values and actual color values in offset printing presses having at least one inking unit and a control computer. The control computer controls the printing speed of the offset printing press and the temperature control of rollers in the inking unit of the offset printing press. The control computer is set up in such a way that, if an inking difference is detected between the setpoint color values and the actual color values, a combined control operation including a change in the printing speed and the temperature in the inking unit is performed in order to compensate for the inking difference. A printing press having the apparatus is also provided.
