    • 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.
    • 方法和系统接收打印作业并确定打印作业是否指定一个或多个扩展色域颜色标记材料。 扩展色域颜色标记材料包括具有除标准着色剂之外的着色剂的标记材料。 标准着色剂由青色,品红色,黄色,黑色(CMYK)组成。 当打印作业没有指定一个或多个扩展色域颜色标记材料时,除了标准着色剂之外,方法和系统确定打印作业是否与一种或多种扩展色域着色剂一起执行得更好。 当打印作业指定扩展色域颜色标记材料时,打印作业使用扩展色域着色剂和标准着色剂打印打印作业,并且当打印作业将通过一个或多个打印系统的扩展色域执行更好的打印作业 着色剂除标准着色剂外。

    • 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.
    • 执行打印引擎校准的方法为打印设备的扫描仪,打印片上的打印测试补丁创建色彩空间转换方程,并使用打印设备的扫描仪扫描测试片,以产生每个测试的扫描的RGB值 补丁。 这样的方法使用颜色空间转换方程将每个扫描的RGB值转换为XYZ伪空间以产生XYZ值。 这些方法将XYZ值与白皮书的第二XYZ值进行比较,以生成相对于白皮书的每个测试贴片的DeltaE曲线。 DeltaE曲线被插值以形成等效的目标曲线。 在确定等效目标曲线之后,方法使用颜色空间转换方程周期性地校准在打印装置类别内的相同或附加打印装置,以产生第二XYZ值。
