  • 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: 9352555
    Abstract: An inkjet printer is provided which can alleviate the degradation of print quality caused by the deviation of ink temperature from a proper temperature range. A controller performs printing while controlling the correspondence of ejection data to nozzle rows so that the ink temperature difference between regions caused by ink ejection operations may be smaller than that in the case where printing is performed with the correspondence of upstream nozzle row ejection data and downstream nozzle row ejection data to an upstream nozzle row and a downstream nozzle row fixed.

  • Patent number: 9277075
    Abstract: In accordance with one embodiment, a color erasing apparatus comprises a conveyance path, a color erasing section and a control section. The conveyance path conveys a sheet. The color erasing section erases the color of an image formed with color erasable recording agent serving as recording agent containing coloring agent the color of which can be erased by heating. The control section carries out a control, in a case where the image formed on the sheet is not an image formed with the color erasable recording agent, so that the sheet is not subjected to a color erasing processing by the color erasing section.
