ABSTRACT:
A method and a device are disclosed for determining a degree of fouling of a printing unit of a printing machine. The method comprises washing a printing unit with a washing medium. A degree of fouling of the washing medium is measured, and a degree of fouling of the printing unit is determined from the degree of fouling of the washing medium. The device for performing the method comprises a translucent conduit, such as a transparent pipe, through which the washing medium in the form of a washing solution is conducted. A light source is disposed on one side of the conduit for shining light through the conduit. An optical sensor is disposed on the other side of the conduit opposite from the light source. The sensor receives the light which permeates the conduit. The degree of absorption of the light in the washing medium is proportional to its degree of soiling.
