A height adjustment assembly is secured onto a supporting frame of the printer table such that an adjustment component…
Virtual ink channels
Granted: May 10, 2016
Patent Number:
9336473
Virtual ink channels are created with colored media and white ink to afford multi-channel ICC profile creation by using ICC profiling software. The available color gamut is enhanced for an device that defines a color space with a color profiler, e.g. an ICC profiler. Thus, an available color gamut for an input or output device is enhanced or extended by creating virtual ink channels for use with profiling software. This allows the use of media types and/or inks that are otherwise not…

Selective ink cure
Granted: April 26, 2016
Patent Number:
9321281
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.
Method and composition for ink jet printing on a nonabsorbent substrate
Granted: April 5, 2016
Patent Number:
9303097
Ink jet printing on a non-absorbent substrate involves a wet primer having a primer viscosity. The wet primer is applied on the non-absorbent substrate. An ink jet ink having an ink jet viscosity lower than the primer viscosity is jetted over the wet primer while the primer is still wet. The wet primer and ink are simultaneously cured on the substrate.
Multilayer white printing with white-balance
Granted: April 5, 2016
Patent Number:
9302490
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…

Such unique number is used in the configuration of a second network device, such as for example a Digital Front End/External Print Controller that may need the IP address of the first network device. The unique number…
Gloss control through selective deposition of transparent ink
Granted: March 1, 2016
Patent Number:
9272541
Embodiments of the invention take advantage of the change in gloss caused by overprinting a printed image with clear ink. Embodiments of the invention thus implement gloss control functionality in a printer without the requirements of a pin and cure or other known systems.
Gloss-controllable, radiation-curable inkjet ink
Granted: February 16, 2016
Patent Number:
9260616
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…
Coupling of digital printer and finishing
Granted: January 12, 2016
Patent Number:
9233569
Various disclosed embodiments relate to structures and methods for printing systems. In some embodiments, a device, e.g., a festoon, may be used to accumulate excess material. The festoon may be located between a print head and a finishing component to eliminate misalignment/mis-registration difficulties between printed images and finishing options. In some embodiments, registration images and other procedures may be used alone or in conjunction with the festoon placement to further…

Embodiments of the invention concern automatic color separation with a white ink for colored and/or transparent substrate, automatic color separation with a silver ink for a natural rendering, automatic color separation with a varnish which has a gloss scale different from that of the printed sample for all shades of gloss that are possible between high glossy to high matte for a false third rendering, automatic color variation with variable thickness under the inks, and variable gamut…
Method and apparatus for controlling lightness in colored inkjet inks by means of a transparent white ink composition
Granted: January 5, 2016
Patent Number:
9228104
A transparent white ink composition is formulated to brighten, lighten and or dilute full-tone primary inkjet colors: cyan; magenta; yellow and black, eliminating the need for ‘light ink’ primary color inks. The transparent white ink is jetted concurrently with reduced amounts of full-tone inks in lighter tonal areas conventionally supported by ‘light ink’ primary inks. Printing ‘light ink’ primary colors using a transparent white ink composition may reduce the number of…
Simulated embossing and imprinting
Granted: January 5, 2016
Patent Number:
9227428
Image processing is used to simulate the appearance of an embossed print. The application of clear dry ink or spot varnish to the print generates the tactile feel of an embossed print. Embodiments thus provide a technique that simulates the effect of an embossed print without the need for plates or specialized equipment, other than a printer that is adapted to apply clear dry ink or spot varnish.
Color prediction for color printing
Granted: November 24, 2015
Patent Number:

Multi-layer printing on non-white backgrounds
Granted: September 8, 2015
Patent Number:
9126420
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.
