摘要： What is disclosed is a novel system and method for converting a set of L*a*b* values to CMYK color space in which all CMYK formulations that produce each L*a*b* value are found and enumerated. The CMYK formulations are found through a search algorithm starting with the lightest L*a*b* values then visiting neighboring L*a*b* values until the entire L*a*b* color set has been processed. The CMYK space is tessellated into a set of pentahedrons, and for each L*a*b* value, an enclosing pentahedron is found and the CMYK values corresponding to where the locus of this point penetrates each surface is recorded. Adjacent pentahedrons are then visited and this process continues until the gamut boundary is reached. The result is a piecewise linear representation of the CMYK locus containing all values that will give the target L*a*b* value. The present method provides a flexible and powerful approach for solving color management problems.

摘要： The teachings as provided herein relate to a watermark embedded in an image that has the property of being relatively indecipherable under normal light, and yet decipherable under infrared illumination when viewed by a suitable infrared sensitive device. This infrared mark entails, a substrate reflective to infrared radiation, and a first colorant mixture and second colorant mixture printed as an image upon the substrate. The first colorant mixture layer in connection with the substrate has a property of strongly reflecting infrared illumination, as well as a property of low contrast under normal illumination against a second colorant mixture as printed in close spatial proximity to the first colorant mixture pattern, such that the resultant image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device.

摘要： A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

摘要： A color output device is generally driven by at least three independent control signals for control of its response. A desired response in device independent color space is normally obtained by employing a cascade consisting of a characterization transform and calibration transform. The calibration transform transforms input control variables into output control variables that are directly used to drive the device. Input control variables can be transformed into intermediate control variables, which can be then mapped to output control variables utilizing a two-dimensional transformation. The two-dimensional calibration architecture provides improved control functionality and flexibility.

摘要： A system and method for printer control and color balance calibration. The system and method address the image quality problems of print engine instability, low quality of color balance and contouring from the calibration. The method includes defining combinations of colorants, such as inks or toners that will be used to print images, defining a desired response for the combinations that are to be used and, in real time, iteratively printing CMY halftone color patches, measuring the printed patches via an in situ sensor and iteratively performing color-balance calibration based on the measurements, accumulating corrections until the measurements are within a predetermined proximity of the desired response. The calibration is performed on the halftones while they are in a high quantization resolution form.

摘要： Methods and systems in an image processing device for controlling colors that are located external to a gamut are disclosed. A plurality of color values can be automatically provided as input to said image processing device, wherein said image processing device is under a control of a particular dimensional order, typically a three-dimensional order, but alternatively can be a two-dimensional order. Next, an operation can be performed dynamically determining which color value among the plurality of color values has attained a gamut limit. Thereafter, the particular dimensional order can be automatically reduced, thereby providing improved control for colors that are located external to said gamut. The plurality of color values analyzed is generally associated with three colors—cyan, magenta, and yellow.

摘要： A show-through reduction method is disclosed. The method is designed to deal with both light and severe show-through. The method focuses mostly on text documents, with characters possibly appearing in multiple gray levels, although the method can also be extended to color documents. As in the prior art, the front and back pages are processed in pairs. However, no perfect page alignment is assumed here, since we are dealing with real images. Instead, a front and back registration is performed as the first step before the pages are further analyzed. In this method, we are aligning the front page content with its show-through appearing in the back side, and the back page content with its show-through appearing in the front side. Once the two sides are aligned, masks are generated for both sides to differentiate severe show-through and light color content regions. Finally, different TRCs are applied to different regions. The show-through is reduced and the page contents are retained.
