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： 4+ color management sequentially processes four colors at a time from among the 4+ colors to leverage solution capability using a 4-color management tools. In methods and apparatus for processing 4+ colors, received information of 4+ colors may be processed in a first stage using four colors of the 4+ colors, such as CMYO. The processed four colors are then mapped into three virtual colors. The mapped three virtual colors and one additional unprocessed color of the 4+ colors are then processed in a second stage using a 4-color tool. From this, a second color model of at least five colors (4+) is generated. The resulting four colors determine five printer colors, and are then mapped into three virtual colors. The mapped three virtual colors and one additional unprocessed color of the 4+ colors are then processed in a third stage using a 4-color tool. From this, a third color model of at least five colors (4+) is generated. This modeling and mapping to virtual input can be repeated for once for each color beyond 4 that is supported by the printer. The processed 4+ colors are output to a device, such as a printing engine, for rendering the image.
摘要翻译： 4+颜色管理从4+颜色中顺次处理四种颜色，以利用四色管理工具来利用解决方案。在用于处理4种颜色的方法和装置中，可以在第一阶段中使用四种颜色的四种颜色（诸如CMYO）来处理接收到的4种颜色的信息。然后将经处理的四种颜色映射成三种虚拟颜色。然后使用4色工具在第二阶段处理4种颜色的映射的三种虚拟颜色和一种其他未处理的颜色。由此产生至少五种颜色（4+）的第二种颜色模型。所得到的四种颜色决定了五种打印机颜色，然后被映射成三种虚拟颜色。然后使用4色工具在第三阶段处理4种颜色的映射的三种虚拟颜色和一种其他未处理的颜色。从此，生成至少五种颜色（4+）的第三种颜色模型。对于由打印机支持的超过4的每种颜色，可以对虚拟输入进行此建模和映射一次。处理的4+颜色被输出到诸如打印引擎的设备，用于渲染图像。

摘要： A color management method, system and storage medium output 4+ color separation signals to a 4+ (5 or more) color print engine. An input source color is converted into virtual intermediate CMYK separation signals using a 4-color management tool, which may be a conventional tool. These virtual intermediate CMYK separation signals are received as input within a digital front end (DFE), which transforms the intermediate signals into 4+ separation signals, such as for a 6-color print engine. A transformation unit of the DFE passes some of the input separation signals through directly as output (without transformation) while transforming others by splitting them into light and dark separation signals, such as light and dark cyan or magenta using a blend curve that will output the same tonal quality. The transformation unit may use a blending curve that takes into account ink-limit constraints and may maximize light colorant usage to improve image smoothness in light image regions.
摘要翻译：色彩管理方法，系统和存储介质将4+颜色分离信号输出到4+（5个或更多）彩色打印引擎。使用四色管理工具将输入源颜色转换成虚拟中间CMYK分离信号，其可以是常规工具。这些虚拟中间CMYK分离信号作为数字前端（DFE）中的输入接收，其将中间信号转换成4+分离信号，例如用于6色打印引擎。 DFE的变换单元通过直接作为输出（无变换）将一些输入分离信号作为输出（而不进行变换），而通过将其分解为亮和暗的分离信号（如浅或深青色或品红色），使用将输出相同的音调质量。变换单元可以使用考虑到油墨限制约束的混合曲线，并且可以使光着色剂的使用最大化，以提高光图像区域中的图像平滑度。

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： In an image processing method, a first raster having a first resolution is divided into a plurality of sub-sampling cells each containing a selected number of neighboring pixels. A pixel from each of the sub-sampling cells is selected in a periodic or quasi-periodic pattern biased toward selecting a pixel position within each sub-sampling cell that is distal from a selection position within at least one neighboring sub sampling cell. The selected pixels define a second raster having a second resolution lower than the first resolution.

摘要： There is disclosed in embodiments methods for halftone dot encoding for engine-dependent-rendering. The methods first carefully design an asymmetric halftone dot for a specific printer and then utilizes a halftone dot encoding algorithm, which encodes the asymmetric halftone dot into a symmetric format. The asymmetric halftone dot design is satisfies the requirements of raster output scanner electronics, as well as several engine dependent constraints. These include: rotation insensitivity, minimum dot size, minimum hole size, minimum appendage, and minimum cavity. The symmetric dot encoding allows perfect reconstruction of the binaries that may have been generated using the original asymmetric dot. This reconstruction is achieved using imbedded binary resolution conversion. In this way, this resolution conversion is acting as a decoder.
