摘要： A method of constructing a screen for halftoning a digitized image is described, in which a composite screen is established. A composite LUT having m times n rank ordered threshold elements is constructed for use in halftoning digitized images. A variety of optimization techniques can be employed to improve the visual appeal of the images rendered using the composite LUT for rendering a variety of image types in single or multicolored imaging applications.

摘要： A process for creating a barcode with an embedded logo considers a printer gamut and divides the printer gamut into multiple regions. A virtual printer gamut is then generated with the colors in bright and dark regions. A target logo image is generated by mapping the virtual gamut to the original logo image. A logo with embedded barcode is produced using the colors specified in the target logo image.

摘要： As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.

摘要： A model-based halftone independent method for characterizing a printer equipped with a plural of halftone screens comprises: printing a target set of basic patches comprised of a fundamental binary pattern independent of a halftone screen; measuring true color printer response from the target set; modeling a halftone independent characterization of the printer with the mathematical transformation using the measured response; modeling a first halftone dependent characterization of the printer with the mathematical transformer to generate a first predicted result using a selected halftone screen; comparing a measured response of the printer using the halftone screen with the predicted result to define a correction factor corresponding to the halftone screen; and modeling a halftone dependent characterization of the printer using a predicted response of the fundamental binary pattern and the correction factor.

摘要： A method for defining a gloss effect in a printed document includes printing a document region with first and second colorant combinations. The first colorant combination defines a first colorant stack height and said second colorant combination defines a second colorant stack height that differs from the first colorant stack height. As such, the document region has a first appearance when viewed straight-on and a second appearance when viewed at an angle. In one example, the first colorant combination is black (K) colorant that results in a one-level stack height and the second colorant combination is cyan, magenta, and yellow (CMY) colorants that result in a three-level stack height. In another example, the second colorant combination can be cyan, magenta, yellow and black (CMYK) colorants that define a four-level stack height. In such case, both colorant combinations appear as black in straight-on viewing or scanning, while the average color and/or luminance of the colorant combinations will differ from each other when the document region is viewed at an oblique angle. The desired gloss font or other gloss effect is defined by selective placement of the first and second colorant combinations relative to each other. Font sizes of 3 points or less can be defined.
摘要翻译：用于在印刷文档中定义光泽效果的方法包括用第一和第二着色剂组合打印文档区域。第一着色剂组合限定第一着色剂堆叠高度，并且所述第二着色剂组合限定与第一着色剂堆叠高度不同的第二着色剂堆叠高度。因此，当从一角度观看时，原稿区域具有直视时的第一外观和第二外观。在一个实例中，第一着色剂组合是导致一级堆叠高度的黑色（K）着色剂，并且第二着色剂组合是导致三级堆叠高度的青色，品红色和黄色（CMY）着色剂。在另一个实例中，第二着色剂组合可以是限定四级堆叠高度的青色，品红色，黄色和黑色（CMYK）着色剂。在这种情况下，两种着色剂组合在直视观察或扫描中显示为黑色，而当以倾斜角度观看原稿区时，着色剂组合的平均颜色和/或亮度将彼此不同。通过相对于彼此选择性地放置第一和第二着色剂组合来限定期望的光泽字体或其它光泽效果。可以定义3点或更少的字体大小。

摘要： As set forth herein, computer-implemented methods and systems facilitate halftoning using a parametrically controlled spot function based on triangle tessellation, which in turn facilitates dot growth control of periodic halftone using an irregular seed structure. The spot function determines the shape of the halftone dot used to reproduce a given pixel. The spot function is well suited for growing halftone dots arrayed on a non-regular grid and can also be used for grids with regular order. The spot function includes adjustable parameters for controlling its sharpness and slope.
