摘要： The present invention relates to providing a designer with the tools for the manipulation of differential gloss in halftoned images. A special mask layer is provided for the rendering of desired glossmark image data. The desired glossmark image data is used to select between two halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density. This selection is made for each corresponding portion of primary image data. In this way, a halftone image of the primary image is generated with glossmarks imbedded therein which will display differential gloss without the need for special toners or paper.

摘要： The present invention relates to the manipulation of differential gloss as may be inherent in halftoned images by utilization of tags. By selectively applying halftones with anisotropic structure characteristics, which are significantly different in orientation while remaining identical in density, as directed by tag settings, a gloss image may be superimposed within an image without the need for special toners or paper. Conventional copier systems will not typically be able to copy such a superimposed gloss image.

摘要： The present invention relates to the segmentation of an image into a main area and a image segment for variable glossmark data. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density to the image segment, a variable glossmark may be superimposed within an image with reduced processing and storage requirements.

摘要： The present invention relates to protecting printed items intended for public exchange having important informational indicia provided therein. The print items are protected from tampering by providing an informational indicia image as a glossmark. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density to render information indicia, a glossmark image is produced of the information indicia. Such an information indicia glossmark image when provided in print item image helps protect that print item image from tampering.

摘要： A method for avoiding objectionable moiré in a color image can include identifying a problematic excitation angle associated with a problematic excitation in a marking process or in the color image and selecting a set of at least two halftone screens for rendering at least two separations of the color image wherein the set of screens is selected to avoid including significant screen fundamental, harmonic and beat frequencies at angles closer than about 1 degree of the identified problematic excitation angle. Halftoning the color image according to the selected set of screens avoids objectionable moiré associated with the problematic excitation.

摘要： Embodiments described herein are directed to detecting and/or measuring distortions of substrate media that can occur during a printing process. The distortion can be detected and/or measured using a composite image generated from a reference image having a first periodic pattern and print image, disposed on a test substrate media, having a second periodic pattern. The first and second periodic patterns are specified so that the composite image includes a moiré pattern having moiré fringes resulting from interference between the first periodic pattern associated with the reference image and the second periodic pattern associated with the print image. The moiré fringes can be used to detect and calculate an amount of distortion of the test substrate media.

摘要： A system and method for the halftoning of gray scale images by utilizing a pixel-by-pixel comparison of the image against an anisotropic stochastic screen is disclosed. The anisotropic stochastic screen comprises a non-deterministic, non-white noise function which, when thresholded, is designed to produce anisotropic dot patterns having a power spectrum characterized as having negligible low frequency components and a high-frequency region which has an absence of stronger dominant spikes.
