Patent number: 10507679Abstract: Techniques for more accurately and efficiently replicating the alignment of one or more printer components with respect to another printer component are described herein. Replication may be achieved by using a fixture and a connection media to create a near exact replica of features of the fixture, or to temporarily hold multiple printer components in position while a joining layer of the connection media hardens. More specifically, a connection media, such as epoxy, can be used to fill an intentionally-established gap between connecting bodies or components that are held in a predetermined position by the replication fixture. The replication fixture represents a mechanical mounting interface that influences the position of a print head (or an array of print heads) within a printer housing or printing mechanism. Joining printer components in such a manner enables a stable mechanical coupling to be formed that does not require post operations.Type: GrantFiled: May 17, 2017Date of Patent: December 17, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventor: John A. Weismantel

Patent number: 10449792Abstract: Mechanisms for adjusting the position of one or more print heads at an extremely fine resolution (e.g., less than 10 ?m) are described herein. The adjustment mechanisms include a differential screw and an indexing wheel through which the differential screw extends. One threaded segment of the differential screw is connected to a threaded feature of a flexible body that is coupled to the print head(s), while another threaded segment of the differential screw is connected to a threaded feature of a rigid body that is coupled to a printer assembly. As the indexing wheel and differential screw rotate, the space between the flexible body and the rigid body changes based on the difference between the pitches of the threaded segments. The adjustment mechanisms described herein utilize the accurate, consistent motion of the flexible body upon experiencing pressure to effect predictable changes in the position of the print head(s).Type: GrantFiled: July 9, 2018Date of Patent: October 22, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventor: John A. Weismantel

Patent number: 10447896Abstract: Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.Type: GrantFiled: May 25, 2017Date of Patent: October 15, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Leon Williams, Thor Olson

Patent number: 10421289Abstract: 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: July 3, 2017Date of Patent: September 24, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Peter Heath, Joseph A. Lahut, Dwight Cram, Bryan Ko

Patent number: 10392524Abstract: Disclosed are compositions, such as inkjet inks, for jetting onto a ceramic substrate, and associated methods and systems. The compositions comprise a pigment compound that is configured to be jetted on a ceramic substrate during a ceramic inkjet process to impart a color effect to the ceramic substrate, and a reduction agent which, when exposed to a firing temperature, reacts with the pigment compound to cause a reduction reaction. In some embodiments, the pigment compound comprises jettable copper particles, which can cause the fired composition to take on a red or oxblood color, which can be used for decoration.Type: GrantFiled: November 20, 2017Date of Patent: August 27, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Mark Zavada, David Weber, Louis Fage, Matthew Tennis

Patent number: 10350911Abstract: Individually controllable ultraviolet (UV) light-emitting diodes (LEDs) are used to cure ink and generate different effects. The UV LEDs only expose specified areas to generate the different effect and can create multiple effects on the same substrate by exposing different areas to varying amounts of time or by performing a curing stage and post-dosage curing stages. The different effects include generating a glossy surface, a matte surface, and sharper images.Type: GrantFiled: January 29, 2018Date of Patent: July 16, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventor: Peter Heath

Patent number: 10300723Abstract: Embodiments include a method performed by a system operative to determine a condition related to a printed section printed by a shuttle-based printer. The method includes printing a portion of an image on a section of a medium, thereby providing a printed section. The section of the medium can have a size defined by at least a step size taken by the shuttle-based printer to advance the medium in a downstream direction. The method also includes scanning at least the printed section to capture a sample image of the printed section. The sample image can be captured by using an imager moving in a direction perpendicular to the downstream direction. The method also includes inspecting at least the sample image to determine a value indicative of a condition related to the printed section.Type: GrantFiled: October 11, 2016Date of Patent: May 28, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Steven A.

Patent number: 10265978Abstract: Edge hold down (EHD) systems are described herein that enable high print quality to be achieved more consistently, particularly when using substrates that are rigid or include one or more defects. Each EHD system includes a tensioned band for holding down an edge of a substrate as it passes through a printer assembly without impacting the print area. The tensioned band can be affixed between an entry tension assembly and an exit tension assembly disposed downstream of the entry tension assembly in the media feed direction. The tensioned band holds the substrate substantially flat against a transfer belt during printing by applying pressure to the surface of the substrate. The tensioned band generally contacts the surface of the substrate substantially proximate to an outer edge that is parallel to the media feed direction.Type: GrantFiled: April 19, 2017Date of Patent: April 23, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Keith Vaillancourt, Christopher Andrew Porter

Patent number: 10179462Abstract: Optimization of ink recipes for spot colors in printers. Often, ICC Profiles are optimized for smooth rendering of images; thus, color recipes often contain more inks than are required for matching a color when generated from a Profile. When transitioning from one color to another, it is better to make smaller changes in inkings. This goal is not served when printing spot colors. Spot colors are often single, solid colors that do not vary in gradients from one to another. Herein is a discussion including dividing an N-ink set into subsets, generating an ink recipe for a desired recipe in each ink subset, and selecting a subset based on predetermined criteria. Where a spot color is out of Gamut, that color is mapped to the Gamut.Type: GrantFiled: May 18, 2017Date of Patent: January 15, 2019Assignee: ELECTRONICS FOR IMAGING, INC.Inventor: Harold Boll
