  • Publication number: 20230370561
    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.

  • Patent number: 11169462
    Abstract: Various variable gloss reduction techniques are disclosed. In one embodiment, a gloss reduction technique is disclosed using a textured roller and a wiper impregnated with fuser oil to create a differential gloss pattern that reduces the gloss of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a combination of heat and pressure to create a differential gloss pattern that reduces the gloss in specific regions of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a differential gloss pattern to generate a security mark on a printed image to prevent against copying or fraudulent misrepresentation of the image.

  • Publication number: 20200337508
    Abstract: In the treatment of human faeces having a starting moisture content, the faeces are pressed between opposing pressing surfaces of rollers in a dryer, to press out at least some moisture from the faeces. The pressing surfaces are moved to leave an exposed layer of pressed faeces on at least one of the pressing surfaces which is then scraped. This produces partially-treated human faeces having a moisture content of not more than 20 wt %. The partially-dried human faeces may then be combusted. This fuel is fed substantially continuously into a combustor at a rate of 0.4-15 g/min combusted continuously over a time of at least 1 hour. In the combustor, there is a reaction chamber with a drying zone and a first combustion zone. The reaction chamber is orientable to permit gravity-assisted transit of the fuel from the drying zone to the first combustion zone. The drying zone has a drying zone grate configured to hold some of the fuel while combustion of other of the fuel occurs at the first combustion zone.

  • Patent number: 9952539
    Abstract: The smoothness of a toner layer is reduced and thus the gloss of a resulting print is reduced. A single toner, the original high gloss version, is enabled to print all images. A finishing option is provided which, through application of a combination of heat and pressure with a textured roller, reduces the specular gloss of the toner surface by imprinting a high frequency texture onto the smooth toner layer. By adjusting the temperature/pressure of the textured roller, the effective gloss of the press can be adjusted through software as desired.

  • Patent number: 9914309
    Abstract: Compensation algorithms are applied to hide failed nozzles or, at least, reduce the objectionable effect of such nozzles in a printed image. Once a failed nozzle or under-performing nozzle is detected in a single-pass printing system, it is shut-off and the image data that was intended to be printed by this nozzle is redistributed to its neighboring nozzles. Embodiments of the invention use of a 1-D look-up table and stochastically distribute the duty cycle to each neighboring nozzle. In this way, failed nozzles are effectively hidden in the final print.

  • Patent number: 9891867
    Abstract: A proxy software service determines all I/O devices independent of subnet location, on a network; provides a network interface on a wireless subnet that can receive and respond to requests; responds to such requests for each I/O device so identified so that the I/O device is available to the wireless device user for device selection; transfers and translates, if necessary, the IPP stream received from the wireless device to the network address of the I/O device so that the I/O device simulates a compliant I/O device; and transfers and translates, if necessary, all necessary status and command messages from the present protocol to the protocol supported by a legacy I/O device.

  • Patent number: 9786094
    Abstract: Limitations of conventional dimensional printing techniques are addressed to provide features and flexibility not presently available, including extracting images selectively from a Postscript® or PDF file and thus enable texturing of individual images within a page; constructing the texture automatically directly from the image using image processing techniques; visualizing the texture to be applied to an image via construction of a bump map or normal map in openGL and DirectX®; adjusting texturing parameters via visual feedback in openGL and DirectX®; and inserting a clear texture back into a PDF file for printing automatically.
