Abstract

Method of ink control in a printing press, includes optically measuring fields on sheets printed by the printing press, comparing an actual ink location for each measuring field, which is attained with the aid of the scanning, with a specified setpoint ink location and controlling inking elements of the printing press so as to reduce deviations in inking. The method further includes calculating film thickness/densities of printing inks required for attaining the setpoint ink location by using the actual ink location and the setpoint ink location; adjusting the inking elements of the printing press in accordance with the calculated film thicknesses/densities, when the setpoint ink location or an ink location within a specified tolerance range about the setpoint ink location is attained, indicating the non-attainment of the setpoint ink location or of the tolerance range about the setpoint ink location, and making a manual input before adjusting the inking elements and subsequently producing a printed sheet and/or further computing film thicknesses/densities.
