摘要： A method for encryption of a digital watermark by intelligent halftoning includes receiving image data that define at least a portion of a document to be printed in terms of at least three halftone images corresponding respectively to three printing colorants, each of the three halftone images comprising a plurality of halftone cells. The image data are modified by phase-shifting some of the halftone cells of at least one of the halftone images relative to the other halftone images to encode a watermark within the portion of the document such that the at least one phase-shifted halftone image includes a phase-shifted region and a non-phase-shifted region. The modified image data are used to print the portion of the document on a substrate that will fluoresce when subjected to UV illumination. The printed portion of the document includes a first printed pattern resulting from the phase-shifted region and a second printed pattern resulting from the non-phase-shifted region. The first and second patterns of the printed portion of the document appear substantially similar when the portion of the document is viewed in visible light, and appear dissimilar when the portion of the document is viewed in UV light such that the watermark encoded in the modified image data is perceptible when the portion of the document is viewed in UV light and is hidden when the portion of the document is viewed in visible light.

摘要： Disclosed herein is a method and apparatus for moiré-free color halftone printing with up to five color image separations. The method and apparatus utilize a plurality of non-orthogonal halftone screens to produce outputs that are moiré free and form rosettes. The method and apparatus provide for defining a first and a second color halftone screen fundamental frequency vector for each of three halftone screens such that the halftone screen set output forms moiré-free rosettes; then defining a fourth color halftone screen where a first fundamental vector of the fourth screen shares a fundamental frequency vector with one of said three halftone screens and a second fundamental frequency vector of the fourth screen shares a fundamental frequency vector with a different one of said three color halftone screens; and further defining a fifth color halftone screen where a first fundamental vector of the fifth screen shares a fundamental frequency vector with one of said three halftone screens and a second fundamental frequency vector of the fifth screen shares a fundamental frequency vector with a different one of said three color halftone screens, and the neither of the fundamental frequency vectors of the fifth screen are equal to either of the fundamental frequency vectors of the fourth screen.

摘要： A method for compensating for color drift in a printer includes determining a first true tone response curve for a color channel when said printer is in a first state. A first estimated tone response curve for the color channel is also determined when said printer is in the first state. A second estimated tone response curve for the color channel is determined when the printer is in a second, color-drifted state relative to the first state. A second true tone response curve for the color channel is mathematically predicted using the first true tone response curve, the first estimated tone response curve, and the second estimated tone response curve. The first and second estimated tone response curves are estimated using a 2×2 printer model. A printing apparatus includes an image processing unit for implementing the color-drift correction process.

摘要： Provided herein are teachings directed to the creation of moiré-based auto-stereoscopic watermarks in rendered images. By choosing different halftone structures, which differ by having different spatial frequencies for each of two delineated partitions in an image, it becomes possible to embed arbitrary binary patterns into printed documents as digital watermarks. The invisible watermarks become moiré auto-stereoscopic images when the prints are viewed through an overlaid transparency “decoder” suitably prepared by virtue of being rendered with a uniform halftone structure having the correct special frequency in relationship with the partition frequencies employed in the printed document.

摘要： As provided herein, there are supplied teachings to systems and methods for resizing a digital uniform rosette halftone image composed of multiple colorant separations, by using uniform rosette halftone tile parameters. One approach entails receiving into a digital imaging system, a digital uniform rosette halftone image and a desired resizing factor for that digital uniform rosette halftone image. Subsequently the system will define uniform rosette cells within the color uniform rosette digital halftone image. From the defined uniform rosette cells, a number of uniform rosette halftone tile seams are determined for manipulation. The orientation of the number of uniform rosette halftone tile seams is dictated by the received desired resizing factor. An energy map of the digital uniform rosette halftone image is determined according to an energy metric derived from the multiple colorant separations. The energy of the number of uniform rosette halftone tile seams within the energy map is determined so as to provide indication of at least one low energy determined uniform rosette halftone tile seam. A resizing of the uniform rosette halftone image by manipulating the at least one low energy determined uniform rosette halftone tile seam is performed so as to obtain a resized uniform rosette halftone image. The resized uniform rosette halftone image may then be printed on a printer.

摘要： An ink set includes a plurality of inks, at least one ink but less than all inks of the ink set including an ink vehicle, colorant and fluorescence agent and remaining additional inks including an ink vehicle, colorant and free of fluorescence agent. At least a first ink grouping and a second ink grouping of the ink set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first ink grouping and the second ink grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first ink grouping as compared to the second ink grouping.
