Abstract: Methods, apparatus and systems for printing an image using an array of nozzles are described. In one example aspect, a printer system includes an array of nozzles and a control device coupled to the array of nozzles. The control device is configured to determine a step size for printing a current section of an image based on a set of masks. The set of masks includes one or more masks used for printing previous sections of the image. The control device is also configured to adjust the set of masks based on a printing mode to be used for the current section of the image. The array of nozzles is configured to print the current section of the image using a combination of the adjusted set of masks.

Abstract: 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).

Abstract: 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 print channels needed to print all four primary colors and the four ‘light ink’ primary colors. Embodiments of the transparent white ink composition may be solvent- or water-based, drying by evaporation of the carrier fluid. Other embodiments may be radiation-curable ink compositions. An inkjet printer includes print carriage and print head assemblies configured for jetting a primary color ink and the transparent white ink in the same pass in correct proportions to achieve a desired effect.

Abstract: Described is a technology for measuring ink film thickness by use of differential lighting between two differently positioned light sources. The technology involves an image capture device, a first set of light emitting diodes (LEDs), and a second set of LEDs, where the image capture device is attached to a printer. The first set of LEDs is positioned in parallel to an image capture axis to illuminate a target object evenly from above with a light perpendicular to the target object (e.g., substrate with deposited ink droplets). The second set of LEDs is positioned to illuminate the target object at an angle, thereby casting a shadow. The image capture device takes two snapshots of the target object, utilizing a different light source (of the two sets of LEDs) for each snapshot. The snapshots are compared to determine the shadow's magnitude and the ink film thickness based on the shadow.

Abstract: The disclosure is related to printing an image as a multi-layered textured image on a substrate. The printing system prints one or more layers of a texture of the image as a base layer on the substrate and the image above the base layer. The base layer includes one or more layers of the texture. The printing system prints the texture using the ink from the print heads of the printing system. The process of printing a multi-layered textured image can include printing one or more layers of texture as a base layer on the substrate, printing one or more layers of white ink above the base layer, and printing one or more layers of the image above the white layers. The printing system can also insert one or more blank layers between different types of layers, e.g., texture layers, white layers and image layers.

Abstract: 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.
