摘要:
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.
摘要(中):
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。
