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.

Abstract: Disclosed are methods that couple effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet. Embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns. Embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.

Abstract: A system uses GPU accessible, high-speed memory to store compressed or raw video printer data. The system transmits this video data over one or more frames of an HDMI interface and a circuit reconstructs the video data for a page from one or more HDMI frames for communication to a printer.

Abstract: Techniques are provided for printing white underbase image data and highlight white image data in one pass using digital printing technologies. The techniques include increasing the white ink in the white only (or near white only) areas of the image data by combining the white underbase image data and the white ink (or near white ink) image data.

Abstract: A raster image processor and a convolutional neural network or other artificial intelligence module operate in parallel. Image data for printing is passed to the raster image processor and the convolutional neural network. The raster image processor translates computer vector files and/or rasterizes bitmaps having higher or lower resolution than the output device to a raster image that includes a matrix of dots a printer can process. The raster image processor generates layers for process inks. The convolutional neural network generates a mask layer, based on the image, that is used by the raster image processor to generate an additional layer for spot colors, object colors, or specialty ink. The mask layer transmitted to the raster image processor generates a spot color layer. The layers generated by the raster image processor and the additional layer for the spot colors and/or specialty inks are combined into a print data file.

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: Disclosed herein is a technique that improves material efficiency in generating garments and textiles that include graphics. A given product is sorted into cut patterns used to assemble the product. Graphics are digitally applied to each cut pattern in order to generate abstract cut patterns including aligned graphics. Blank cut patterns are nested across a virtual sheet of fabric in a 2D space without any consideration to the graphics. The nested cut patterns implement the abstract cut patterns that include graphics. The graphics are aligned to the positions of the cut patterns according to the nesting scheme. Print instructions including nested cut patterns with aligned graphics are delivered to a printer that executes the print job. The cut patterns are cut away from the fabric sheet including graphic designs that are aligned with the cut patterns.

Abstract: In a color printing environment, functions for printing color management are dissociated. An abstraction layer is also provided to facilitate setting and evaluation of all factors relating to color print and prediction.
