    摘要： A system/method of color match assessment for electronic documents includes receiving digital data defining a composite electronic document including a raster image object having an edge and a color graphics object bordering the edge of the raster image object. The pixel color values defining the edge of the raster image object are processed to estimate a local color variance of the pixel color values. The local color variance is used to determine if the edge can be color matched to the bordering color graphics object. If the edge can be color matched, a match color for the edge is derived. The match color is associated with the digital data defining the electronic document so that a downstream object color match system can use the match color as needed, e.g., to adjust the color of the bordering color graphics object to ensure a match with the edge of the raster image object when the electronic document is printed using a xerographic printing process.

    摘要： Methods and systems of assessing color gamut requirements for a print job and a printing device are disclosed. A print job including one or more input color spaces may be received. A computing device may produce a color transformation for each input color space using at least a color gamut error profile. The computing device may further produce result information based on the one or more color transformations. Result information may be provided to a user.

    摘要： A raster image target tracking method, the raster image being a binary raster image or a targeted contone raster image, may include determining target information that corresponds to a target device for the raster image, saving the target information in a memory, comprising the raster image target device to a processing device by which the document is to be processed, and providing a warning message when the document target device does not correspond to the processing device. Also, a compound document analysis and target tracking method may include providing a compound document, analyzing each object of the compound document to determine target information, saving the target information in a memory, comparing the target devices of the respective objects to each other, and providing a warning message to a user when the target devices of the respective objects do not correspond to each other.

    摘要： A method for correcting a white line artifact between low and high frequency printed pixels. A printer may be able to print either a high or low frequency halftone pixels in some locations, but may be able to print only high frequency halftone pixels in other locations, the latter known as out of phase locations. If the image data is in run length encoded form, and the printer tries to print a low frequency pixel in an out of phase location, no pixel will be printed in that location and a white space results. The remedy is to test at the beginning and end of low frequency runs bordering high frequency runs. If the first (last) low frequency pixel of an original run is in an out of phase location, a one pixel run of the high frequency screen and of the low frequency color is added before (after) the original run, and the run length of the low frequency run is decreased by one pixel.

    摘要翻译： 一种用于校正低频和高频印刷像素之间的白线伪迹的方法。 打印机可能能够在某些位置打印高频或低频半色调像素，但是可以仅在其它位置（后者称为异相位置）中仅打印高频半色调像素。 如果图像数据是运行长度编码形式，并且打印机尝试在异相位置中打印低频像素，则不会在该位置打印像素并产生空白空间。 补救措施是在高频运行的低频运行的开始和结束时进行测试。 如果原始运行的第一（最后）低频像素处于异相位置，则在原始运行之前（之后）添加高频屏幕和低频颜色的一个像素运行，并且运行长度 的低频运行减少了一个像素。
