Patent number: 8960886Abstract: An inkjet printing system includes a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers. The print head includes a substrate and a barrier layer disposed on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. The barrier layer includes a material selected from epoxy-based photo resist materials and methyl methacrylate-based photo resist materials. An orifice plate is disposed over the substrate. The orifice plate includes the plurality of orifices in fluid communication with the ejection chambers. The system includes a reservoir containing an organic solvent-based ink composition, wherein the ink composition includes an organic solvent selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof, in an amount 60% or more by weight of the ink composition.Type: GrantFiled: January 7, 2014Date of Patent: February 24, 2015Assignee: Videojet Technologies Inc.Inventors: Terry M. Lambright, Anthony Selmeczy, Francis Chee-Shuen Lee, Charles C. Haluzak, Kenneth E. Trueba

Patent number: 8794750Abstract: An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member.Type: GrantFiled: May 10, 2013Date of Patent: August 5, 2014Assignee: VideoJet Technologies Inc.Inventors: Charles W. Gilson, Thomas E. Kimerling, Mark R. Thackray, Kenneth E. Trueba, Scott T. Benigni, John P. Folkers, Matthew David Beasley, Terry M. Lambright, Kevin Kuester
