Abstract: What is disclosed is a novel system and method for retrieving a gamut mapping strategy from a seed profile of a seed device. In a manner more fully described herein, the present method provides an embodiment which accounts for the pathological case of a false gamut mapping ray being produced in those instances where the shapes of the gamuts of the host and seed devices are substantially different. In these instances, the rays miss the boundary surface of the host gamut and intersect the boundary of the L*a*b* cube. Another embodiment is provided which accounts for those cases wherein the ray intersects the host gamut at a substantially oblique angle such that mapped color is sufficiently different to generate contours in the output print.

Abstract: What is disclosed is a novel system and method for generating a reference color difference quantity guide for spot color print applications. RCDQ values are determined for spot colors obtained from a library of spot colors. A reference color difference quantity guide is created from the spot colors and their respective RCDQ values in a manner more fully disclosed herein. Thereafter, when a user desires to render a job in a particular spot color, the associated RCDQ value for that spot color can be obtained from the reference color difference quantity guide. In various embodiments, recommendations in the form of a suggested printer to use, a media type, a halftone screen, and other meaningful assistance can be provided for selection of spot colors for a given print/copy job that are less sensitive to varying illuminations. The present RCDQ guide provides meaningful extensions in color reproduction in diverse print/copy job environments.

Abstract: A method for estimating the color of a coated print includes: measuring the color of an uncoated print with a color measuring device; and estimating the color of the print when coated by a coating process based on the uncoated color measurement using a function that correlates uncoated color measurements and coated color measurements; and adjusting at least one parameter of the printing process based on the coated color estimation. The correlating function may be derived by measuring the color of a plurality of uncoated color patches; measuring the color of the plurality of patches after the patches have been coated by the coating process; and correlating the color of the coated patches with the uncoated patches based on the coated and uncoated color patch measurements.

Abstract: What is disclosed is a novel system and method of inheriting intended GCR into a 4-to-4 cascaded LUT to compensate for print engine change which adversely impacts the quality of an output print. The present method uses the device link transform to generate starting LUT nodes for the inverse of the drifted printer model by inputting CMYK or RGB into the device link at a color space resolution sufficient to determine output nodes. Lab and CMYK values are derived from this process, and a “starting LUT” is created at the Lab destination nodes. An iterative control begins with this starting LUT to produce an inverse drifted printer model that contains a close approximation for the intended GCR. The present method captures the intent of the device link transform for a fleet and generates the cascaded LUT for drift, specific printer, side1/side2, and other modes leading to special GCRs.

Abstract translation: 所公开的是将期望的GCR继承到4对4级联LUT中以补偿不利地影响输出打印质量的打印引擎改变的新型系统和方法。 本方法使用设备链接变换通过以足以确定输出节点的颜色空间分辨率将CMYK或RGB输入到设备链接中来生成漂移的打印机模型的倒数的起始LUT节点。 实验室和CMYK值是从该过程得到的，并且在实验室目标节点处创建一个“起始LUT”。 迭代控制开始于该起始LUT以产生包含对于预期GCR的近似近似的反漂移打印机模型。 本方法捕获了针对车队的设备链接变换的意图，并生成用于漂移，特定打印机，side1 / side2和导致特殊GCR的其他模式的级联LUT。
