Patent ID: 8176847

Claim:
A method for checking the plausibility of at least one measured value determined in a printing press and indicating an ink applied to a print substrate transported through the printing press, including the steps of: applying said ink to the print substrate in multiple inking zones; determining a first measured ink density value for a specific ink in a first selected inking zone of the specific ink; determining a second measured ink density value for the specific ink in a second selected inking zone of the same ink; forming a relation between the first measured ink density value determined for the specific ink in the first selected inking zone and the second measured ink density value determined for the same ink in at least the second selected inking zone by placing the first measured ink density value determined for the specific ink in the first selected ink zone in a ratio with the second measured ink density value for the same ink in at least the second selected inking zone belonging to the same inking unit; providing a control device for regulation of the ink in the ink zones for the same ink; rejecting the measured ink density value determined for the specific ink in the selected inking zone as being implausible by the control device if the relation of said measured value from the measured value determined for the same ink in the at least one other inking zone one of exceeds and falls below at least one predefined threshold value; not using said determined implausible measured ink density value in the control device for automatically regulating the ink in the selected ink zone in the printing press when the relation one of exceeds and falls below the at least one predetermined threshold value; and using the measured ink density value in said control device for automatically regulating the ink when the relation is not rejected.
