摘要： Methods and systems receive a print job and determine whether the print job specifies one or more extended gamut color marking materials. The extended gamut color marking materials comprise marking materials having colorants other than standard colorants. The standard colorants consist of cyan, magenta, yellow, black (CMYK). When the print job does not specify one or more of the extended gamut color marking materials, the methods and systems determine whether the print job will perform better with one or more of the extended gamut colorants in addition to the standard colorants. The methods and systems print the print job use the extended gamut colorant(s) and the standard colorants when the print job specifies the extended gamut color marking material, and when the print job will perform better with one or more of the print system's extended gamut colorants in addition to the standard colorants.

摘要： Test image data is introduced into the image processing path of a marking device, at various points prior to the marking engine. Comparison of output of the marking engine from various sources of image data is made to diagnose imaging path component failure. Imaging data at various points in the image processing path is captured for analysis as part of component failure diagnosis. Various memory devices are used to both introduce test data at various points in the image processing path and capture data at various points of the image processing path.

摘要： Methods of performing print engine calibration create a color space conversion equation for a scanner of a class of printing devices, print test patches on a sheet, and scan the test patches using a scanner of the printing device to produce a scanned RGB value for each test patch. Such methods convert each scanned RGB value to an XYZ pseudo space using the color space conversion equation to produce XYZ values. These methods compare the XYZ values to second XYZ values of white paper to generate DeltaE curves for each of the test patches relative to white paper. The DeltaE curves are interpolated to form an equivalent aim curve. After the equivalent aim curve is determined, the methods periodically calibrate the same or an additional printing device that is within the class of printing devices using the color space conversion equation to produce second XYZ values.

摘要： Disclosed herein is an image processing method for producing enhanced halftone edges, particularly suited to those edges which only lie upon the background as apposed to those edges which abut other halftone screens. It utilizes a step of defining border pixels and a step of halftoning those border pixels in a different manner than the halftoning applied to the interior region of the tint or image segment. The preferred halftone for the border pixels will be related to the interior halftone by some number of common spatial frequency harmonics. Examples of common-harmonic screening for an edge include, but are not limited to: (a) same screen with different tone reproduction characteristics (boosted edge values); (b) same screen angles and frequencies with a different spot function, possibly phase shifted; (c) a dot screen whose frequency vectors can be generated by the frequency vectors of the interior screen; (d) a line screen whose frequency vectors can be generated by the frequency vectors of the interior screen. This generation process is directed to ensuring that the two screens will be “harmonically matched” where at least one of the fundamental frequency vectors and harmonics of the first screen will equal at least one of the fundamental frequency vectors and harmonics of the second screen.
摘要翻译：本文公开了一种用于生产增强的半色调边缘的图像处理方法，特别适合于仅靠在与其它半色调屏幕相邻的那些边缘上的背景的那些边缘。它利用定义边框像素的步骤和以与应用于色调或图像片段的内部区域的半色调不同的方式对这些边界像素进行半色调的步骤。用于边框像素的优选半色调将通过若干数量的共同空间频率谐波与内部半色调相关。用于边缘的共谐波筛选的示例包括但不限于：（a）具有不同色调再现特性（增强边缘值）的相同屏幕; （b）具有不同光点功能的相同屏幕角度和频率，可能相移; （c）可以通过内部画面的频率矢量生成频率矢量的点画面; （d）可以通过内部画面的频率矢量生成其频率矢量的行画面。该生成处理旨在确保两个屏幕将被“谐波匹配”，其中基本频率矢量和第一屏幕的谐波中的至少一个将等于第二屏幕的基本频率矢量和谐波中的至少一个。

摘要： Method, system and computer-readable medium containing instructions for performing halftone gamma correction in a printing environment to achieve and maintain high print quality. The system includes one or more subsystems, including a tone reproduction subsystem that creates one or more print calibration pages, each having a tone curve defining a relationship between a plurality of input color levels, output color levels and a level of measured darkness. A pixel adjustment subsystem associates each input color level with one of the output color levels based on a desired percentage change in the level of measured darkness. Further, a gamma correction system performs gamma correction on a selected tone curve of one of the print calibration pages by associating each input color level with one of the output color levels based on the desired percentage change in the level of measured darkness in a substantially flat region of the selected tone curve.
