摘要： A device for acquiring color images using a color filter array. The color filter array includes a pattern of red array elements, green array elements, and blue array elements. The red array elements and green array elements occur in the color filter array more frequently than the blue array elements. This multiplicity of red, green, and blue color filters adheres closely to known human visual system (HVS) chrominance and luminance responses. Also, the pattern has periodicity in the diagonal directions and is relatively immune to Moire artifacts that arise due to interference between periodic sampling patterns of the CFA and periodic features in imaged scenes.

摘要： A method and system are provided for producing a print that substantially corresponds to the colorimetric attributes of a corresponding proof for an electronic source file. The method and system entail creating a first raster file corresponding to the electronic source file and a second raster file corresponding to the proof. The first and second raster files are aligned to insure a spatial correlation, and a color conversion data structure is built by comparing the aligned first and second raster files. The color conversion data structure is then used to convert the first raster file to a color converted output file. The color converted output file is color transformed to an output file which is then used to produce the print. The print substantially corresponds to the colorimetric attributes of the corresponding proof for the electronic source file.

摘要： A method and system for estimating color separation misregistration of a printing system. The method may include marking a substrate to form a misregistration estimation patch. The misregistration estimation patch being formed by first and second color separations. The first color separation marking the substrate with a first halftone pattern. The first halftone pattern has a first halftone-frequency vector in a first direction and a second halftone-frequency vector in a second direction. The second color separation marking the substrate with a second halftone pattern. The second halftone pattern has a first halftone-frequency vector in a first direction and a second halftone-frequency vector in a second direction. The first and second halftone patterns form a moiré pattern. A deviation in at least one the halftone frequency vectors and/or the moiré pattern can be indicative of a color separation misregistration. The method also includes estimating the color separation misregistration of the printing system using the misregistration estimation patch.

摘要： A system and method is provided for characterizing color separation misregistration associated with marking a substrate. The method includes providing an input image having a plurality of patches, each patch having a pattern using a first and second color; marking a substrate with a copy of the input image using a first and second color separation to correspond to the first and second colors, respectively; and measuring a color characteristic of markings of respective copied patches of the copied plurality of patches and generating corresponding colorimetric values. Misregistration of the first color separation markings relative to the second color separation markings is characterized based on the measured calorimetric values.

摘要： A method of simulating a differential gloss image includes providing a background and a gloss effect image. The gloss effect image is configured for controlling the selective application of first and second halftones to the background image for creation of a differential gloss image when the background image is printed. A mask based on the background image is formed in which regions of mid-tone gray level are accentuated. An edge effect filter may be applied to the gloss effect image to form a filtered gloss effect image. The mask is applied to the filtered gloss effect image to generate a background modified filtered gloss effect image. The background modified filtered gloss effect image is applied to the background image to generate a representation which simulates the differential gloss image.

摘要： A method is provided for characterizing color separation misregistration of a printer device, the method including receiving from the printer device an output image having marked calibration patches having a variety of color separation configurations, each using a first and second color separation, and a marked measurement patch having a predetermined color separation configuration. Measured colorimetric values are received corresponding to the calibration patches and the marked measurement patch, and a characteristic of a curve associated with the measured colorimetric values corresponding to the calibration patches is determined. A calibration function is generated based on the determined characteristic of the curve, providing expected colorimetric values for the predetermined color separation configuration as related to a misregistration characteristic value. A misregistration characteristic value is determined from the calibration function that corresponds to the measured colorimetric value of the marked measurement patch for characterizing misregistration between the first and second color separations.
