摘要： Identifying the substrate type of a target substrate before patterning by a marking engine produces an opportunity to adjust the marking engine. The adjustments can enable the marking engine to produce higher quality work. The target substrate's substrate type can be automatically identified by obtaining its characteristics and submitting them to a classifier. A spectrophotometer can measure a substrates reflectance spectrum, which is a good characteristic for use in classifying. Classifiers can be based on known distance or correlation measures.

摘要： The teachings as provided herein relate to a watermark embedded in an image 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.

摘要： Systems and methods are described that facilitate real-time personalization of an electronic image by overlaying a text string on a planar surface of an object in the electronic image. A linear or affine transform is executed on a selected text string to position the text string in a reference rectangle or text box. A non-linear or projective transform is applied to the rectangular text box to project the box into a user-defined quadrilateral on the planar surface in the image. A page description language (PDL) file is generated and includes the transformed quadrilateral text box overlaid on the electronic image. At print-time, a database (e.g., a spreadsheet or the like) containing multiple text strings is read, once for each text string, and multiple images are printed. Each printed image has one of the text strings overlaid thereon, on the planar surface defined by the quadrilateral.

摘要： A method and system for identifying a fluorescence mark in a printed document includes using an image acquisition device to derive an input digital image that represents a printed document including a background and a fluorescence mark adjacent the background. The input digital image includes multiple color channel digital images, with each color channel digital image comprising a plurality of pixels each defined by a gray value. For each pixel of at least one of the color channel digital images, the gray value is adjusted based upon a variance of adjacent pixel gray values to define a filtered digital image including a plurality of pixels each defined by an adjusted gray value. Some pixels of the filtered digital image correspond to low variance regions of the input digital image and other pixels of the filtered digital image correspond to high variance regions of the input digital image. A binary image is derived that represents the filtered digital image by mapping each adjusted gray value of the filtered image to either a first or second possible binary pixel value. The binary image includes a binary representation of the fluorescence mark and a binary representation of the background. At least one morphological operation is performed on the binary image to adjust the pixel values of the binary representation of the background so that all pixel values of the binary representation of the background are opposite the binary pixel value used for the binary representation of the fluorescence mark. An ASCII character for the binary representation of the fluorescence mark (or each constituent character thereof) can be derived and compared to a known security code to authenticate the printed document.

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.
