  • Publication number: 20200032906
    Abstract: The invention relates to a sealing element for an ink chamber of a rotary printing press, wherein the sealing element has a sealing surface that rests against a roller body during operation of the rotary printing press. In order to reduce wear on the sealing element, the sealing surface has at least one flow outlet opening, at which an overpressure of a fluid may be built up during operation of the rotary printing press, in such a way that the fluid between the sealing surface and roller body forms a sealing flow film.

  • 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.
