Publication number: 20230286294Abstract: Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.Type: ApplicationFiled: February 27, 2023Publication date: September 14, 2023Inventors: Lianhui Cong, Terrill Clayton

Patent number: 9260616Abstract: Gloss-controllable, radiation-curable inkjet inks cure quickly with minimal radiation exposure, enabling high-printing speed and low surface heating with controllable gloss on the printed image. Ink gloss can be controlled by varying the pinning energy to create the printed images with varied gloss from 10 to 100 gloss unit at 85° gloss measurement angle. After curing, the ink remains flexible on the surface, giving excellent performance on a wide range of surfaces, greatly expanding the range of applications for the ink. A gloss-controllable, radiation-curable inkjet ink may include approximately 8-18% of photo-initiators responding to UVA and UVV (UVA: 320-400 nm wavelengths, UVV: 400-450 nm wavelengths) radiation to initiate free radicals and optionally, other types of photo-initiators and approximately 60-85% of highly flexible mono-functional monomers.Type: GrantFiled: February 29, 2012Date of Patent: February 16, 2016Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Lianhui Cong, Daniel Francis Gloster, Paul Andrew Edwards

Patent number: 9085161Abstract: Enhanced printing systems, structures, and processes provide ultrasonication of ink, such as to degas the ink, and/or to maintain the size of particles within the ink. At least one ultrasonic module, such as comprising any of an ultrasonic probe or an ultrasonic bath, is located within an ink delivery system. Ink is delivered to the ultrasonic module, and ultrasonic energy is applied to the ink, such as at a sufficient level and duration to degas the ink, and/or to reduce the size of particles within the ink. In some embodiments, the particles may be agglomerates, wherein the applied energy is configured to reduce the size of the agglomerates to a size that can be jetted through the print head. In other embodiments, the particles may be metallic particles, wherein the applied energy is configured to create smaller metallic particles that can be jetted with the ink through the print head.Type: GrantFiled: June 7, 2013Date of Patent: July 21, 2015Assignee: Electronics for Imaging, Inc.Inventors: Daniel F. Gloster, Paul Andrew Edwards, Lianhui Cong, Michael R. Quint
