Abstract
An apparatus for measuring zonal inking on a printed product having a plurality of inking zones includes a plurality of optical sensors, each of the optical sensors picking up signals from at least one zonal measurement region assigned to a respective one of the plurality of inking zones of the printed product. The apparatus also includes 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 the at least one optical switch for receiving the picked up signals and evaluating the picked up signals.
Claims12
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;
- 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.
The apparatus of claim I, wherein each of the inking zones of the printed product to be measured is assigned to a respective one of the plurality of optical sensors.
A method for measuring the zonal inking on a printed product, comprising the steps of:
- picking up signals from zonal measurement regions using a plurality of optical sensors;
- passing the picked up signals to a common measuring device with the interposition of at least one optical switch;
- and
- measuring, by at least one measuring device, the picked up signals;
- and
- evaluating the picked up signals at the measuring device to determine the zonal inking.
