Abstract:
1. A method of controlling metering of ink in offset printing presses having printing units, at least one ink metering device in each printing unit, and a control unit, the method comprising the following steps: measuring a measuring strip including a plurality of gray measuring fields in different continuous tones within an ink zone on a printed product, with a color measuring device, the gray measuring fields being disposed in at least two parallel rows, each gray measuring field present in a first row of the at least two parallel rows being present at least once in each further row of the at least two parallel rows; feeding measured gray values to the control unit for controlling the metering of the ink in the printing units; calculating nominal values for controlling the metering of the ink in the printing units with the control unit and transmitting the nominal values to the printing units; and controlling the metering of the ink in the printing units based upon the nominal values.
