摘要： Using a system of computer modules operatively associated with a document processing machine, banding defect analysis is accomplished by analyzing specific test patterns via image processing. The banding defects are characterized in terms of quantitative parameters based on an analysis of the banding defect. Key features are extracted from the banding defect parameters. The key features are analyzed in a diagnostic engine, to determine the possible source of the defect. The identified source is correlated to a recommended repair service procedure. The diagnostic process may be augmented by also including machine data in the analysis.

摘要： The present invention is directed to a system and method for test target selection in conjunction with dynamic test pattern generation. In the invention, a test pattern page(s) is composed using an optimal set of test targets, which can be accommodated or adjusted to fit within size constraints of the test pattern. The method of the present invention makes use of layout optimization to ensure that related and optimized test targets are accommodated on a single test pattern. For example, it may be preferable to “squeeze in” a smaller-than-normal uniform area target, rather than not to print it at all during a test.
摘要翻译：本发明涉及一种结合动态测试图形生成的测试目标选择的系统和方法。在本发明中，测试图案页面是使用最佳的一组测试目标来构成的，该测试目标可被容纳或调整以适应测试图案的尺寸限制。本发明的方法利用布局优化来确保相关和优化的测试目标被容纳在单个测试图案上。例如，优选的是“挤压”小于正常的均匀面积目标，而不是在测试期间根本不打印它。

摘要： A special test pattern and image quality analysis system and process for evaluating the test pattern are provided to accurately measure color-color registration in an image output device that prints in CMYK color. The process is robust even when using relatively low-resolution CCD-based scanners and also is unique in that the process automatically factors out errors originating from skew between the detector and the subject of measurement. Further, registration of each of C, M, and Y relative to K are independently determined. The test pattern includes an upper part and a lower part, with both the upper and lower parts having a black K component and the upper part also including color components for C, M and Y. The system and method have potential for being built in to color printers or copiers to allow measurement of color misregistration within the paper path and automatically correct for color registration errors.

摘要： An ink key simulator for image forming devices may simulate the effect of ink key adjustments in offset presses. The image adjustment may be made in response to activation of a simulated ink key, for example, by adjusting the pixel values of the stored data and/or by adjusting imaging light source intensity within a given region of the image. Using the ink key simulator, adjustments to image quality from printers may be made on-the-fly using an interface which is familiar to the operators of offset presses.

摘要： A method of adjusting an image production system to account for a variable property of a desired output medium includes storing a reference characterization of at least one measured value associated with a reference output medium. An output value, adjusted for the variable property of the desired output medium, is determined based on data including the reference characterization of the reference output medium, for example stored in color lookup tables, color rendering dictionaries, or the like. Based on the adjusted output value determined, the desired output medium is then printed or otherwise marked using the output value.

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.
