  • Publication number: 20220091796
    Abstract: A printing apparatus includes a head part, an encoder, a tension sensor, a head part temperature sensor, an edge sensor, an estimation part, a storage, and an output part. The estimation part estimates print quality in terms of a page printed by the head part on the basis of variation elements detected by the encoder, the tension sensor, the head part temperature sensor, and the edge sensor. The storage stores print quality information containing the printed page and the print quality estimated by the estimation part in association with each other. The output part outputs the print quality information to a display, a post-processing device, and a printer controller section.

  • Publication number: 20220068627
    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.
