Patent ID: 7980175

Claim:
An apparatus for measuring zonal inking on a printed product having a plurality of inking zones, comprising: a plurality of optical sensors picking up signals from zonal measurement regions assigned to the plurality of inking zones of the printed product, wherein at least one of: each of the inking zones of the printed product to be measured is assigned to a respective one of the plural optical sensors, and at least two of the plural inking zones are assigned to a common optical sensor of said plural optical sensors, said common optical sensor being movable along said at least two of the plural inking zones; at least one optical switch connected for receiving the picked up signals from the plurality of optical sensors; and at least one measurement device connected to said at least one optical switch for receiving the picked up signals and evaluating the picked up signals, wherein the apparatus is disposed in a press for printing the printed product, the apparatus automatically measuring the zonal inking on the printed product during a printing process of the printed product in the press, and said plurality of optical sensors are divided into a plurality of groups of optical sensors, each of said plurality of groups being connected to a respective optical switch, and each said respective optical switch being connected to only a single common measuring device, wherein a further optical switch is connected between each of said respective optical switch and said single common measuring device.
