Patent number: 10472533Abstract: Novel inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process, are disclosed. The novel ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent. The second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.Type: GrantFiled: February 6, 2017Date of Patent: November 12, 2019Assignee: Kornit Digital Ltd.Inventors: Jacob Mozel, Jacob Mann, Muhammad Iraqi

Patent number: 10391784Abstract: Method and apparatus for digital printing of textiles with application of immobilization compound on the textile prior to printing. The method comprises, finding failed printing nozzles; carrying out immobilization of the textile without using at least some of the nozzles neighboring a failed printing nozzle; and printing the textile. The immobilization generally prevents the printing ink from running, so leaving out immobilization around the failed nozzle allows ink to seep into the unprinted gap. The immobilization however also stabilizes the ink, so one embodiment keeps some of the neighboring nozzles on during the immobilization.Type: GrantFiled: October 5, 2016Date of Patent: August 27, 2019Assignee: Kornit Digital Ltd.Inventors: Ofer Ben-Zur, Miri Gerenrot

Publication number: 20190169794Abstract: Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.Type: ApplicationFiled: February 5, 2019Publication date: June 6, 2019Applicant: Kornit Digital Ltd.Inventor: Donald D. SLOAN

Publication number: 20180339510Abstract: A modular textile printing apparatus is made up of multiple modules which are combined together. Each module has one rail for bearing a printing functional unit such as a print head. A second rail perpendicular to the first rail faces the first rail, and carries a printing tray or platen holding items to be printed. The tray moves along the rail. A third rail parallel to said second rail and facing away from the printing functional unit, is also for carrying the tray. The modules are connected together and the apparatus provides a starting point for loading and unloading the trays. The second rails are aligned with each other to form a continuous printing feed along the modules and the third rails are aligned to provide a return path after printing to the starting point for reloading.Type: ApplicationFiled: November 9, 2016Publication date: November 29, 2018Applicant: Kornit Digital Ltd.Inventors: Ofer BEN-ZUR, Alon Feldman, Ohad SNIR
