Patent number: 11712901Abstract: White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).Type: GrantFiled: May 28, 2021Date of Patent: August 1, 2023Assignee: Fiery, LLCInventors: Peter Heath, Joseph A. Lahut, Dwight Cram, Bryan Ko

Patent number: 9126420Abstract: In a multi-layer printer, the base white layer that is applied during printing is modified using the image to be printed. By altering the white layer to reflect the density of the top image, it is easier to reach saturation (density/gamut) without adding large amounts of ink. Thus, such undesirable side effects, such as gloss-banding are avoided.Type: GrantFiled: June 4, 2013Date of Patent: September 8, 2015Assignee: Electronics for Imaging, Inc.Inventors: Peter Heath, Dwight Cram, Bryan Ko, Joseph A.

Patent number: 8684511Abstract: Gloss is controlled in UV ink jet printing within a printing system. Controlled pinning energy is used to adjust the amount of ink interaction between drops, substrate, and ink layers, resulting in virtual elimination of gloss banding and control of the finished gloss level from a gloss level of approximately 85 to a gloss level of approximately 5.Type: GrantFiled: August 25, 2011Date of Patent: April 1, 2014Assignee: Electronics for Imaging, Inc.Inventors: Joseph A. Lahut, Dwight Cram, John Duffield, Peter Heath

Patent number: 8672451Abstract: Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput, but the nozzles are arranged so that any given square inch of substrate to which ink is being applied receives a lower amount of ink. A longer effective print head is provided by arranging the print heads into a longer array, where the print heads are butted substantially end-to-end. As a result, the net throughput of the printer is the same as that of a conventional printer because the printer uses the same number of print heads, but the amount of ink that is applied to any given square inch is less on a pass.Type: GrantFiled: May 20, 2013Date of Patent: March 18, 2014Assignee: Electronics for Imaging, Inc.Inventors: Joseph A.
