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 infrared illumination when viewed by a suitable infrared sensitive device. This infrared mark entails, a substrate reflective to infrared radiation, and a first colorant mixture and second colorant mixture printed as an image upon the substrate. The first colorant mixture layer in connection with the substrate has a property of strongly reflecting infrared illumination, as well as a property of low contrast under normal illumination against a second colorant mixture as printed in close spatial proximity to the first colorant mixture pattern, such that the resultant image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device.
摘要翻译：本文提供的教导涉及嵌入在图像中的水印，其具有在正常光线下相对不可破译的性质，并且在由合适的红外敏感设备观看时在红外照明下可解码。该红外线标记需要反射红外辐射的基板，以及作为图像印刷在基板上的第一着色剂混合物和第二着色剂混合物。与基底相关的第一着色剂混合物层具有强烈反射红外照明的性质，以及在正常照射下对第二着色剂混合物的低对比度的性质，其与第一着色剂混合物图案紧密相邻地印刷，使得适当地暴露于红外照明的所得到的图像渲染基板将产生作为适合的红外敏感装置的红外标记显而易见的可识别图像。

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。

摘要： A toner set includes a plurality of toners, at least one toner but less than all toners of the toner set including binder, colorant and fluorescence agent and remaining additional toners including binder, colorant and free of fluorescence agent. At least a first toner grouping and a second toner grouping of the toner 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 toner grouping and the second toner 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 toner grouping as compared to the second toner grouping.

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.
摘要翻译：这里描述的是以独立于设备的方式使用PDL内的命名颜色字典来编码红外（IR）安全水印的方法。选择一组颜色位于普通色域的打印设备中，然后在与设备无关的色彩空间中定义。对于每种颜色和输出设备，使用反演技术获得对应于最小和最大黑色（K）的同成色体对的器件着色剂值。选择这些极值以获得最大可感知的IR信号。处理同色异体对集以提取满足某些标准的较小子集，包括K差异的界限，总油墨面积覆盖率和与中性轴的偏差。然后将最终数据存储在将固定的与设备无关的IR颜色名称链接到可变设备相关着色剂值对的资源文件中。

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 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.
