Patent number: 11707943Abstract: A method of indirect digital printing is disclosed herein. The method employs (i) first (e.g. transparent) and second aqueous ink components (comprising colorant particles) and (ii) a target surface (e.g. hydrophobic) of an intermediate transfer member (ITM). A quantity of first ink component is deposited (e.g. by ink-jetting) onto the target surface and partially dried to produce a partially-dried layer thereon. Droplets of the second ink component are deposited onto the partially-dried layer of first ink component to form a wet, colored ink-image. Upon deposition of the droplets of the second ink component, the colorant particles from the second component penetrate into the partially-dried layer of the first ink component. The wet, colored image is dried into a tacky ink-image-bearing residue film which is transferred to the substrate. Physical and/or chemical properties of the first and second ink components as provided by various embodiments are disclosed herein.Type: GrantFiled: May 12, 2018Date of Patent: July 25, 2023Assignee: LANDA CORPORATION LTD.Inventors: Moshe Levanon, Tal Shimony-Cohen, Yelena Yusupov, Natalia Zlotnikov

Patent number: 11660880Abstract: The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.Type: GrantFiled: December 1, 2021Date of Patent: May 30, 2023Assignee: Guangzhou Pulisi Technology Co., Ltd.Inventors: Xiaobo Lin, Lu Liu, Zhenhua Meng

Patent number: 11642898Abstract: A printer control unit controls a fan, based on an acquired reference temperature and an output of a sensor, to cause a temperature of a platen drum or a temperature of a sheet supported by the platen drum to be the reference temperature. Specifically, at step S100, the printer control unit acquires a type of the printing medium to be used for printing, acquires the reference temperature at step S110, and at step S150, controls an operating state of the fan, based on the temperature of the platen drum output by the sensor, such that the temperature of the platen drum becomes the reference temperature acquired at step S110. As a result, a temperature increase of the platen drum becomes substantially saturated at the targeted reference temperature.Type: GrantFiled: December 20, 2021Date of Patent: May 9, 2023Assignee: Seiko Epson CorporationInventors: Kenji Otokita, Takahiro Imai
