Abstract
A material, with at least one identification characteristic, is subjected to a qualitative evaluation. A color image of this at least one identification characteristic is taken using an electronic image sensor which produces an electrical signal that is evaluated by an evaluation device. Another electrical signal is obtained from at least one reference image and is stored in a data memory. The second electric signal, has a set point value, for the first electric signal, for at least two set point values contained in the reference image. The first signal is compared to at least two set point values in the second image. The color image of the identification characteristic is tested for deviation from the reference. The identification characteristic is checked for association with at least one aspect of the identification characteristic of the material. The tasks are carried out in a continuous working process being carried out by a machine, such as a printing machine, during a continuous printing process.
