Abstract: A software application corrects for luminance and/or color in a captured image on a device having two cameras. The first camera receives a reference image, and the second camera receives a target image. The device compares the reference image and a reference file retrieved from memory to identify one or more luminance or color differences, and it automatically actuates an optical adjustment element of the second imaging device in response to the differences. The second imaging device captures a target image, and the target image is stored in a computer-readable memory.

Abstract: A grayscale two-dimensional barcode may be converted to a two-dimensional color barcode. The color barcode includes a set of sub-regions, and the cells in each sub-region exhibits a color pattern that corresponds to pattern of binary, grayscale cells. The two-dimensional color barcode may be decoded by comparing the pattern for each sub-region to a known grayscale pattern. The two-dimensional color barcode may be used for error correction by first decoding the barcode in grayscale form based on the luminance without reference to color, then decoding the barcode based on its color and comparing the results.

Abstract: What is disclosed is a novel system and method for generating a spectral matching guide for spot color print applications. Spectral matching values are determined for spot colors obtained from a library of spot colors. A spectral matching guide is created from the spot colors and their respective spectral matching values in a manner more fully disclosed herein. Thereafter, when a user desires to render a job in a particular spot color, the associated spectral matching value for that spot color can be obtained from the spectral matching guide. In other embodiments, recommendations in the form of a suggested printer to use, a media type, a halftone screen, and other meaningful assistance can be provided for selection of spot colors for a given print/copy job that are less sensitive to varying illuminations. The present spectral matching guide provides meaningful extensions in spectral color reproduction in print/copy job environments.

Abstract: Methods are provided for creating a fluorescent watermark within an image on a substrate, such as paper. The method involves creating a halftone image using two different halftone strategies. The halftone method is combined with a binary watermark mask to form two color patterns (e.g., one in a background region of the image and one in a watermark region of the image) and two successive-filling halftone algorithms, such that the ink droplets deposited by one color pattern cover more of the substrate than the ink droplets deposited by the other color pattern, with the two color patterns having approximately the same reflectance under normal light. However, under UV illumination, a visible difference (e.g., the watermark) is seen in the two patterns.

Abstract: The teachings as provided herein relate to a watermark embedded in an image, and methodology for same, that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first dot design printed as an image upon the substrate. The first dot design has as a characteristic, the property of strongly suppressing substrate fluorescence. A second dot design having a property of providing a differing level of substrate fluorescence suppression from that of the first dot design such that when rendered in close spatial proximity with the first dot design image print, the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

Abstract: The appearance of a color print viewed under UV illumination is predicted using a target comprising color patches each printed using a known coverage of printer colorant(s). In one case, the target is illuminated using a UV light source and an electronic image of the target is captured using a digital camera or the like. In another case, a spectrophotometer is used both with and without a UV cutoff filter to measure the target. The captured image data or the spectrophotometric measurements are used to derive a UV printer characterization model that relates any arbitrary combination of printer colorants to a predicted UV color appearance value. Metameric colorant mixture pairs for visible light and UV light viewing can be determined using the UV model together with a conventional visible light printer characterization model. A visual matching task is used to determine a correction factor for the UV printer characterization model.
