摘要： A print defect management device that supports job-specific print defect management automatically assesses print job pages to determine the severity of image quality defects likely to occur on one or more selected printers. Views of identified troubled pages may be rendered to include approximations of color and image quality defects based on the original page image data, and each printer's color rendition data and defect data, thereby allowing troubled pages for one or more selected printers to be viewed prior to printing. Suggested changes may be automatically or manually applied. Once satisfied with the image quality of print job pages rendered for a specific printer, a user may submit the print job to the same printer, thereby assuring that the user's image quality expectations are met in the printed product. The device may support job-specific print defect management with both local and/or remote printers via LAN, WAN and/or Internet based connectivity.

摘要： What is disclosed is a novel system and method for determining and capturing the designer intended colors in an image so that the printer has an accurate color rendition target. The present method operates by capturing the monitor RGB values together with the monitor profile to get a representation of the intended image in a device-independent color space like L*a*b*. The teachings hereof work for vector graphics as well as raster images. Advantageously, this invention solves a real problem currently existing, for example, in the packaging print market, wherein colors produced from multiple spot colors with their overlays and blends are not well color managed.
摘要翻译：公开的是用于确定和捕获图像中的设计者预期颜色的新型系统和方法，使得打印机具有准确的色彩再现目标。本方法通过将监视器RGB值与监视器配置文件一起捕获来操作，以在与设备无关的颜色空间（如L * a * b *）中获得所需图像的表示。这里的教学工作用于矢量图形以及光栅图像。有利地，本发明解决了例如在包装印刷市场中存在的真实问题，其中由具有它们的覆盖物和共混物的多种专色产生的颜色不是很好的颜色管理。

摘要： A system and method detect missing inkjets in an inkjet image generating system. The system and method generate digital images of printed documents that do not have test pattern data within them. The digital images are processed to detect light streaks and the positions of the light streaks are correlated to inkjet positions in printheads. Identification of the ink color associated with the correlated inkjet positions are obtained with analysis of color separated images and/or color errors.

摘要： What is disclosed is a novel system and method for determining color profiles based upon optimizing output image spatial noise. For each of a number of selected output colors, spatial noise values for a set of device-dependent color specifications that produce the selected output color are iteratively determined. The set of device-dependent color specifications is generated by varying a subset of colorants in the device-dependent color specifications while changing the remaining colorants to maintain the selected output color. The iterative process improves the spatial noise value, as determined by a spatial noise model, of the device-dependent color specifications that correspond to the selected output color. When an optimum spatial noise value is found, the device-dependent color specification having that spatial noise value is selected as the mapping for the selected device-independent color specification. Various embodiments are disclosed.

摘要： A spot color dictionary is fine tuned or updated. Localized color production models are determined for spot colors of interest to be produced by an associated document processing system or printer. Measurements are made of colors of produced spot colors. Optionally, measurements are made of colors of test patches that are based on perturbations from the colors of the spot colors. In determining a model for the production of a target spot color, measurement data related to colors that are closer in color space to a given target color is given a higher weight than is measurement data related to colors that are further in color space from the target color. Accordingly, the model is localized to the region of color space about the target color and therefore, more accurately predicts a colorant recipe for the target color than would interpolation based on a full gamut, or more general model.

摘要： For a selected class of functions, which describe most typical banding variations, the average response can be found by sampling at only 2Nth locations, where N is the number of different frequencies of significant banding. This approach makes use of the fact that in most applications the banding frequencies of a given printer system, are known in advance, even if the amplitudes of the banding are not known. Each sample point requires a very small test area or pattern, significantly reducing the overall size of the required test areas.
摘要翻译：对于描述最典型的条带变化的所选类别的函数，可以通过仅在第2N个位置进行采样来找到平均响应，其中N是显着条带的不同频率的数量。这种方法利用了在大多数应用中，给定打印机系统的条带频率是预先已知的事实，即使条带的振幅是未知的。每个采样点需要非常小的测试区域或图案，显着降低了所需测试区域的总体尺寸。
