  • Publication number: 20230302830
    Abstract: A printing apparatus includes a transport unit that intermittently transports a medium, a support portion that supports the medium, a head that performs printing by discharging a liquid onto the medium supported by the support portion during a period in which the transport of the medium by the transport unit is stopped, a carriage at which the head is mounted and that moves relative to the medium, and a control unit. The control unit causes the head to discharge the liquid onto a printing region while moving the carriage, the printing region being a region, of the medium, supported by the support portion, and starts the transport of the medium by the transport unit after the discharge of the liquid by the head is completed and before the carriage stops.

  • Patent number: 11610771
    Abstract: A device for emitting ultraviolet light includes at least one excimer lamp and a housing for the excimer lamp(s). Each excimer lamp has a discharge vessel filled with light-emitting gases, and a pair of first and second electrodes that are placed in contact with the discharge vessel and produce a dielectric barrier discharge inside the discharge vessel. The housing is made of an insulating and heat-resistant resin material. The housing is configured to house the excimer lamp(s), and has a light-emitting window that allows light with a center wavelength in a range from 200 nm to 230 nm emitted from the excimer lamp(s) to exit from the housing.

  • Patent number: 11373293
    Abstract: A method for building an image determination model that determines whether a print image is a good image or a failure image includes a step of determining whether the print image is a high-density image or a low-density image; a step of generating teaching data by combining pseudo-failure data with to-be-combined image data, based on a result of the determination; and a step of performing machine learning. Regarding the combining of the pseudo-failure data, for a print image determined to be the high-density image, low-density pseudo-failure data is combined with to-be-combined image data, and for a print image determined to be the low-density image, high-density pseudo-failure data is combined with to-be-combined image data.
