    Abstract: 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.

    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: Various embodiments concern inkjet printing systems designed for multilayer imaging with a high-gloss clear ink layer. More specifically, the inkjet printing systems are designed so that clear, curable inks are provided additional time to level out before being cured. The settling process enables the inkjet printing systems to produce multilayer images having high gloss values. For example, a bracket could be attached to a curing assembly that prevents radiation from striking a certain portion of the substrate onto which clear ink has recently been deposited. As another example, an inactive array of light-emitting diodes may be disposed in line with the print head(s) responsible for depositing clear ink. Moreover, various embodiments also allow for true multilayer printing of a color coat and a high-gloss clear coat in a single step (e.g., by arranging print heads into rows within a printer carriage).

    Abstract: Apparatuses and embodiments related to compensated laser cutting of labels. A computer system receives an image of a label, and rasterizes the image. The computer system determines how much of each type of printer ink of a label printer to deposit at each pixel location of the image. The computer system determines which pixels intersect a cut line, and determines the characteristics of the ink of the pixels, such as the quantity or thickness of the ink at the pixel locations. The computer system determines laser data including power, cut speed, and/or frequency of a laser that is tuned to accurately cut through the ink that forms the image, the material(s) of the label, and the adhesive that removably adheres the label to base material(s), but to not excessively damage the base material(s). A laser cutting system uses the laser data to control a laser.

    Abstract: 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.
