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: 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.

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.

Abstract: Techniques are provided that allow the user to view on his or her mobile device the body of an email or other items from a message service as well as each of the attachments as thumbnails or individual images. As well, techniques allow the user to view particular attributes of each item, e.g. the number of pages and the page size of a particular attachment. Techniques are provided such that the user may view such thumbnails and/or attributes on a unique URL generated as a result of the generated email. Thus, by such techniques, the user is provided with a platform for mobile devices that allows intuitive selection of what should be or is desired to be printed.

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.

Abstract: An embodiment implements a methodology for printing non-saturated text and lines in a way that removes the jagged edge problem. An embodiment uses a combination of two screens, e.g. AM screening and applying pure color. For example, according to the embodiment, the closer to the edge from the interior of text or lines, the less amplitude modulation half toning is applied and the more actual color or contone is applied. A particular algorithm for determining and using a blending parameter is provided.
