    • A method for creating a pattern color space for use during print job processing may include: a) defining a variable portion of the pattern color space, b) defining a fixed portion of the pattern color space, c) defining a bounding shape for the pattern color space, d) defining a procedure for painting the variable and fixed portions within the bounding shape, and e) at least temporarily, saving the pattern color space to a storage device. The variable portion of the pattern color space may be based on variable data associated with the print job and an object within the print job may identify the pattern color space for a color parameter. A system using this method may include a storage device, a digital front end, a print controller, and a print engine. Various methods for using the pattern color space during print job processing are also provided.

    • Disclosed are methods and apparatus for providing extended functionality to a networked device, the networked device connected in a network, as well as corresponding apparatus and computer-readable medium. The embodiments intercept data communications in which the networked device is a party, the data communications being intercepted by an interdictor, receive at the interdictor a subscription registration for notification of a networked device event which is to be altered, the subscription registration being received from an extension service, determine whether the data communications in which the networked device is a party corresponds to the subscription registration of the networked device event which is to be altered, and modify the data communications in which the networked device is a party to provide the extended functionality when the data communications are determined to correspond to the subscription registration of networked device event to be altered. According to one exemplary embodiment, the event is altered to include a security feature within a document associated with a print job.

    • 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.
    • 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。
