摘要： As set forth herein, a computer-implemented method facilitates replacing text on cylindrical or curved surfaces in images. For instance, the user is first asked to perform a multi-click selection of a polygon to bound the text. A triangulation scheme is carried out to identify the pixels. Segmentation and erasing algorithms are then applied. The ellipses are estimated accurately through constrained least squares fitting. A 3D framework for rendering the text, including the central projection pinhole camera model and specification of the cylindrical object, is generated. These parameters are jointly estimated from the fitted ellipses as well as the two vertical edges of the cylinder. The personalized text is wrapped around the cylinder and subsequently rendered.

摘要： Described herein is a method to encode infrared (IR) security watermarks using a named color dictionary within a PDL in a device independent manner. A set of colors is chosen that lies within the common gamut of printing devices and then defined in a device-independent color space. For each color and output device, a metameric pair of device colorant values corresponding to minimum and maximum black (K) is obtained using inversion techniques. These extremes are selected in order to obtain the maximum perceivable IR signal. The metameric pair sets are processed to extract a smaller subset that satisfies certain criteria, including bounds on the K difference, total ink area coverage, and deviation from the neutral axis. The final data is then stored in resource files that link fixed device-independent IR color names to pairs of variable device-dependent colorant values.

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. For each pixel of at least one of the input image color channels, the gray value is adjusted to define a filtered digital image including a plurality of pixels each defined by an adjusted gray value. A binary image is derived that that represents the filtered digital image. 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. An ASCII character for the binary representation of the fluorescence mark (or each constituent character thereof) is derived and compared to a known security code to authenticate the printed document.

摘要： A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.

摘要： A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

摘要： A variable data pantograph is formed by receiving a variable data string and retrieving at least one character representation from a vocabulary of character representations stored in memory. The retrieved at least one character representation corresponds to the variable data string. Each of the character representations in the vocabulary is associated with a foreground region including a character shape and a background region suitably sized and arranged for encompassing the foreground region. The background region incorporates a first pattern of elements and is controlled to render a target color using a first set of color separation control data and the foreground region incorporates a second pattern of elements and is controlled to render the target color using a second set of color separation control data. The retrieved at least one character representation is assembled to form a variable data pantograph, whereby when the variable data pantograph is rendered in an original document, the foreground and background regions are similar in tone, the foreground and background regions being substantially less similar in tone in a copy of the original document to render the character visible.

摘要： A method and system are provided for including a double layer security mark in digital document data defining an image of a document to be printed and in the printed document, itself. A fluorescence mark region including a fluorescence mark is defined using first and second metameric colorant mixtures. Variation in colorant spatial coverage between the first and second metameric colorant mixtures results in colorant-free areas that define the fluorescence mark due to substrate fluorescence under UV illumination. The fluorescence mark region is modified to define a double layer fluorescence mark region including the fluorescence mark and also including at least one visible light object defined by a third colorant mixture. The third colorant mixture is added to the fluorescence mark region by masking the colorant-free areas of the fluorescence mark region to prevent writing of the third colorant mixture data to the colorant-free areas so as not to disturb the colorant-free areas.

摘要： A method for defining a gloss effect in a printed document includes printing a document region with first and second colorant combinations. The first colorant combination defines a first colorant stack height and said second colorant combination defines a second colorant stack height that differs from the first colorant stack height. As such, the document region has a first appearance when viewed straight-on and a second appearance when viewed at an angle. In one example, the first colorant combination is black (K) colorant that results in a one-level stack height and the second colorant combination is cyan, magenta, and yellow (CMY) colorants that result in a three-level stack height. In another example, the second colorant combination can be cyan, magenta, yellow and black (CMYK) colorants that define a four-level stack height. In such case, both colorant combinations appear as black in straight-on viewing or scanning, while the average color and/or luminance of the colorant combinations will differ from each other when the document region is viewed at an oblique angle. The desired gloss font or other gloss effect is defined by selective placement of the first and second colorant combinations relative to each other. Font sizes of 3 points or less can be defined.
摘要翻译：用于在印刷文档中定义光泽效果的方法包括用第一和第二着色剂组合打印文档区域。第一着色剂组合限定第一着色剂堆叠高度，并且所述第二着色剂组合限定与第一着色剂堆叠高度不同的第二着色剂堆叠高度。因此，当从一角度观看时，原稿区域具有直视时的第一外观和第二外观。在一个实例中，第一着色剂组合是导致一级堆叠高度的黑色（K）着色剂，并且第二着色剂组合是导致三级堆叠高度的青色，品红色和黄色（CMY）着色剂。在另一个实例中，第二着色剂组合可以是限定四级堆叠高度的青色，品红色，黄色和黑色（CMYK）着色剂。在这种情况下，两种着色剂组合在直视观察或扫描中显示为黑色，而当以倾斜角度观看原稿区时，着色剂组合的平均颜色和/或亮度将彼此不同。通过相对于彼此选择性地放置第一和第二着色剂组合来限定期望的光泽字体或其它光泽效果。可以定义3点或更少的字体大小。
