摘要： A first series of control patches is printed with a first marking engine. A second series of control patches is printed with a second marking engine. Relative reflectance values of the patches printed with the first and second marking engines are measured with respective first and second engine response sensors. Based at least on a difference in the measured relative reflectance values of the control patches printed with the first and second marking engines, a relative engine to engine error is determined. The engine to engine error is decomposed into components. Based on the decomposition, adjustment of at least binary values of a digital image is determined so that print density of a first marking engine output substantially matches print density of a second marking engine output.

摘要： A method adapts image data using more than eight bits per pixel to be compatible with devices using only 8-bit per pixel data. The method separates the higher bit depth data into an 8-bit image data stream, the balance of the bits are carried in a separate tag data stream. The 8-bit image data stream can be used in legacy devices that can handle only 8-bit data, and the tag data stream can be used in legacy devices that incorporate a tag data stream for their internal image processing.

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： A xerogrpahic system and method use a tri-level development process in which at least one xerographic imaging unit includes a photoreceptor and a pair of developer units. A first developer unit includes a conventional first toner of a given color (CYMK) and a second developer unit includes a hypochromatic light form of the first toner. By use of a specific tri-level process, excellent color-to-color registration can be achieved for each processed color separation because overlap between colorants can be prevented. Moreover, by use of two forms of the same colorant, a smoother tone reproduction curve can be achieved when an aggressive blending strategy is used. Gamut loss and ink limit violation can be avoided by adjusting the blending curve in certain situations. An exemplary implementation uses a four drum, eight color tandem architecture with formulations of Cyan, Magenta, Yellow and Black, as well as corresponding hypochromatic light colorants of light Cyan, light Magenta, light Yellow, and light Black (gray).
摘要翻译： Xerogrpahic系统和方法使用三级开发过程，其中至少一个静电复印成像单元包括感光体和一对显影单元。第一显影剂单元包括常规的给定颜色的第一调色剂（CYMK），第二显影剂单元包括第一调色剂的低色光。通过使用特定的三级方法，由于可以防止着色剂之间的重叠，因此可以对每个经处理的颜色分离实现优异的颜色到颜色配准。此外，通过使用两种形式的相同着色剂，当使用积极的混合策略时，可以实现更平滑的色调再现曲线。通过在某些情况下调整混合曲线可以避免色域损失和墨水极限违规。示例性实施方案使用具有青色，品红色，黄色和黑色制剂的四鼓八色串联结构，以及浅青色，浅洋红色，浅黄色和浅黑色（灰色）的相应色素浅色着色剂。

摘要： A method and system for converting, transforming or translating an imaging element associated with a first resolution into a second imaging element associated with a second resolution are provided. The method and system provide for the selection of output imaging element pattern based on context information extracted from areas neighboring an area undergoing conversion when information extracted from the area undergoing conversion provides an insufficient basis from which to select an output imaging element pattern. Exemplary embodiments are directed toward preservation of area coverage and centroid placement. The method provides for consideration of characteristics of a marking engine in the output imagine element pattern selections process. In xerographic environments clustering can be maximized, thereby reducing xerographic stress. In inkjet environments output pattern selections can be directed toward decreased clustering.
