Abstract
A method of operating a printing press includes transferring ink from an inlet point to a printing substrate, and measuring actual optical values of light, in which the actual optical values are from light of selected wavelength ranges and in which the light has interacted with at least parts of the printed image. The method includes providing a control and evaluation device with measured values from an optical measuring device and with measured values from an ink mass determination device so as to determine an optical deviation of actual optical values from optical reference values, and determining an amount of corrective ink that is to be fed to the printing press in order to approximate the actual optical values to the optical reference values.
