Web-fed rotary printing press with at least one inking unit and with an in-line inspection system

, said sensors (-fed rotary printing machine having at least an inking unit and with an in-line inspection system, wherein the at least one inking a printing ink for printing a print image on a printing material web (03) that provides the in-line inspection system a plurality of sensors (12 11) 11; 12) extending row are in a laterally (to a transport direction of the printing material 03), said sensors (11; 12) respectively detect the printed hue of (on the printing substrate 03) the print image, wherein the sensors (11; 12 12 are formed), in each case, the three discrete photosensitive areas having a mutually different spectral sensitivity, each color sensor (11;) in each case as a three discrete photosensitive areas comprising forming color sensor (11 12) as its respective output signal provides a value triples, wherein each triplet a measurement value (x, y, z) of each of the three discrete li contains chtempfindlichen regions, each color sensor (11; 12) which the triplet forming measured values (x; y; z detected) at the same time, the output signal of a single (in the number of the color sensors 11, 12) randomly arranged selected color sensor (11; 12), or simultaneously the respective output signal more in this series arbitrarily arranged selected color sensors (11; 12) can be tapped, wherein one of the color sensors (11; 12) carried data acquisition downstream data processing unit is provided, wherein the respective output signal of a plurality of color sensors (11; 12) is detectable by this data processing unit, characterized in that that the data processing unit on the basis of a set in their filter at least one of the color sensors (11; 12) selects only the output signal of the selected color sensor (11; 12) or only the respective output signal of the selected color sensors (11; 12) is detected, wherein the data processing unit in form one or more freely programmable Logi kschaltkreise is formed (FPGA), and that a measured value amplifier (14) the respective output signal of the color sensors (11; amplified 12) by a gain factor where the gain factor for the respective output signal of which is arranged in the same row color sensors (11; 12) is different configured.
