  • LIQUID NITROGEN JET STREAM PROCESSING OF SUBSTRATES
    Publication number: 20180297229
    Abstract: The present disclosure relates to processing a substrate including at least one sheet of paper, cardboard or carton by directing a jet stream of liquid nitrogen to a surface of the substrate via a jet nozzle; and by moving the jet nozzle at a distance from the surface. The jet stream can be unmodulated or modulated. For example, the jet stream can be modulated by a modulation unit such as to reduce the impact of the jet stream on the surface. In this way, the jet stream can be applied to score folding lines into the substrate. An unmodulated or on/off modulated jet stream can be applied to cut lines into the substrate. Thus, by applying an appropriate modulation to the jet stream, the processing can switch between cutting the substrate and scoring folding lines into the substrate.

  • Display Device
    Publication number: 20180275478
    Abstract: One example of a display device includes an electronic paper display, a counter-electrode, a floating electrode, and a patterned layer. The electronic paper display is imageable by receiving charges on an imaging surface of the electronic paper display. The counter-electrode is opposite to the imaging surface of the electronic paper display. The floating electrode is capacitively coupled to the counter-electrode. The patterned layer on the floating electrode provides mechanical protection for the floating electrode while enabling an air discharge to the floating electrode.

  • GENERATING A HALFTONE
    Publication number: 20180152596
    Abstract: In one example, halftone data comprising first data and second data representing a plurality of pixels in a halftone is generated. The first data associates a first subset of the plurality of pixels in the halftone with a first colorant, the first subset defining a first region in the halftone. The second data associates a second subset of the plurality of pixels in the halftone with a second colorant different from the first colorant, the second subset defining a second region in the halftone. The first subset of the plurality of pixels in the halftone and the second subset of the plurality of pixels in the halftone are mutually exclusive, and the first region is at least partially enclosed by the second region.

  • GENERATING A HALFTONE
    Publication number: 20180141345
    Abstract: In one example, a first subset of a plurality of pixels in a halftone is determined to be associated with a first colorant. A second subset of the plurality of pixels in the halftone is determined to be associated with a second colorant, the second colorant being different from the first colorant. Pixel data associating a pixel in the plurality of pixels in the halftone with the first colorant and not the second colorant is generated when the pixel is included in the first subset and the second subset. Pixel data associating the pixel in the plurality of pixels in the halftone with the second colorant and not the first colorant is generated when the pixel is included in the second subset and not the first subset.
