    摘要: A method for regulating inking of a printing press. The method includes a first step of providing a picture taking device, a closed-loop control device, and a printed product having a surface with a printed image. A second step of printing a print control strip on the surface next to the printed image. A third step of deriving first picture signals from the print control strip and deriving second picture signals from the printed image with the picture taking device. A fourth step of using the closed-loop control device for deriving actual values representing inking of the print control strip from the first picture signals and comparing the actual values to desired values for deriving resultant comparison values. A fifth step of determining ink adjusting signals for controlling ink distribution devices from the resultant comparison values for varying inking of the print product until a desired value is reached during a printer tuning phase. A sixth step of generating an OK signal when the desired value is reached. A seventh step of using the closed-loop control device for deriving further actual values representing inking of the printed image from the second picture signals and comparing the further actual values to further desired values for creating further resultant comparison values. Lastly, one determines further ink adjusting signals for controlling the ink distribution devices from the further resultant comparison values for varying inking of the printed product.
