  • Patent number: 11146804
    Abstract: A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

    Abstract: A method prints and dries a substrate where ink containing water and pigment is printed onto the substrate in an inkjet printing process. The substrate has an initial moisture content and absorbs at least water of the ink, causing the moisture content of the substrate to rise. Radiation selectively acting on the water molecules is applied in a first drying step and then radiation selectively acting on the pigment is applied in a second drying step in such a way that after completion of the two drying steps, the water of the applied ink has essentially completely evaporated and the substrate has essentially reattained its initial moisture content. In this manner optimum drying of substrates to which ink has been applied occurs.

  • Patent number: 10792923
    Abstract: Certain examples described herein relate to calibrating a cleaning element for a printhead. A print medium sensor is aligned with a nozzle plane of the printhead to detect displacement, during a print job, of a print medium out of the nozzle plane. Relative movement between the cleaning element and the printhead is enacted. During this movement, activation of the print medium sensor is detected. A reference position for the cleaning element is stored based on the detected activation.

  • Patent number: 10787010
    Abstract: A print media feeding apparatus includes a stacking part configured to stack print media; a feeding roller which is movable to an abutting position at which the feeding roller contacts the print media stacked on the stacking part and to a separated position separated from the print media stacked on the stacking part and configured to feed a print medium by rotating at the abutting position; a separation member configured to separate the print media; and a return unit configured to perform a return operation of returning the print medium other than a top print medium which the feeding roller abuts. The feeding roller moves to the separated position after feeding the print medium from the stacking part. The return unit performs the return operation upon the feeding roller moving to the separated position. After the return operation, the feeding roller stops at the abutting position.

  • Patent number: 10773537
    Abstract: The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes “print as you glide” (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.

  • Patent number: 10752457
    Abstract: An ink jet card printer includes an ink jet print head, a gantry, and a card feeder. The ink jet print head is configured to perform a print operation on a card supported in a print position along a processing axis. The gantry is configured to move the print head through a print zone. The card feeder includes a feeder frame, a first pinch roller pair, and a lift mechanism. The first pinch roller pair is supported by the feeder frame and is configured to feed individual cards along a card feed axis. The lift mechanism is configured to move the feeder frame and the first pinch roller pair between a lowered position, in which the card feeder is displaced from the print zone, and a raised position, in which at least a portion of the card feeder extends into the print zone.

  • Patent number: 10696059
    Abstract: A printing apparatus is provided that prints a print target on a medium made of chemical fiber fabric. The printing apparatus includes inkjet heads which are chromatic color heads that eject inks having chromatic colors, and an inkjet head which is a black color head that ejects ink having black color. The inks ejected from these inkjet heads are allowed to dry by evaporation and each contain a solvent and a coloring material for expressing the ink color. The inks are dried by evaporating the solvents in the inks to be fixed to the medium. The chromatic color heads include at least six or more inkjet heads that respectively eject the inks having chromatic colors distinct from each other.

  • Patent number: 10661583
    Abstract: A printing apparatus, including a conveyor, a liquid ejection head with nozzles, a contact part to contact a surface of a recording medium and a controller, is provided. The controller executes printing processes including a first printing process with a first conveying action and a second printing process with a second conveying action. The controller obtains a length of a non-printing region in the recording medium, and in the second printing process, designates a nozzle within a contact range, in which the recording medium is maintained contacted by the contact part upon completion of the conveying action in a final printing process, to be a second nozzle, which is activated to print a most downstream part of the image. The longer the length of the non-printing region is, the closer nozzle closer to an upstream end of conveyance among the plurality of nozzles is designated to be the second nozzle.
