  • Patent number: 9358777
    Abstract: A system for measuring the viscosity of printing ink during a printing and ink correction process includes a printing press having an ink supply system, and an optical measuring device for measuring actual optical values of light that has interacted with at least parts of the printing picture. The printing press has an ink mass determination device to determine the weight of at least parts of the ink located in the ink supply system, and a control and evaluation device to receive measured values from the optical measuring device and from the ink mass determination device. The control and evaluation device determines an optical deviation, and, based on the optical deviation and the values from the weighing devices, an amount of corrective ink that is to be fed to the printing press in order to approximate the actual optical values to optical reference values.

  • Patent number: 8708439
    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.

  • Publication number: 20110035040
    Abstract: The invention relates to a system and a method for controlling the composition of an ink mixture for at least one printing press, in which actual optical value of light are obtained, whereat the light has interacted at least with parts of the printing picture, which is generated by the printing press on the printing substrate using an ink mixture which is provided by an ink supply system and in which, due to the deviation of the actual optical value from optical reference values, a corrective ink mixture is created, which is added to the ink mixture which is provided by the ink supply system and which changes the ratio of the amounts of ink pigments therein, whereby first actual optical values are obtained inline, that is at running and just printed printing substrate, wherein these actual optical values are densitometrical values.
