If the grey component is replaced by black ink, the same color is being achieved by using two primaries and black. The substitution of black for the grey component is described as grey component replacement (GCR). [1] In GCR, contrary to under color removal (UCR), the CMY values that add to grey all along the tone scale can be replaced with ...

gcr是一种用适量的k来替代可察觉非彩色cmy部分的黑版生成技术。 可以把所有的颜色都看成是由两部分—非彩色(灰色)成分和彩色成分组成。 非彩色成分可以由混合的CMYK来印刷。

2005年2月6日 · UCR and GCR are the two standard black generation stratigies used for CMYK printing. UCR stands for Under Color Removal. UCR separations use the K ink only for neutral or near-neutral colors.

Gray Component Replacement (GCR)is the separation technique to replace cyan, magenta and yellow wherever they overprint to produce neutral gray. This process is also known as achromatic color separation .

GCR (Gray Component Replacement) 的手法與 UCR 類似，它不是新的技術，早在 1980 年代就被廣泛使用了。 其與 UCR 最大的差別在於所處理的範圍，UCR 只針對暗部階調部份做取代，並不影響亮部和中間調。

2017年4月1日 · In four color printing, gray component replacement (GCR) is a method of replacing the achromatic component of a mixture of chromatic inks by a corresponding amount of the achromatic ink. Simple approaches to GCR lead to unacceptable color shifts.

The advantages of the use of GCR include: Ink savings (black ink is less costly than CMY inks, and GCR enables less ink to be used overall), Color stability (Printing is less susceptible to color changes and shifts.)

2007年5月12日 · Gray Component Replacement, abbreviated GCR, is a technique for replacing gray tones otherwise made from yellow, cyan and magenta separations instead with black ink. Black ink can be less costly than CMY inks. Brighter colors can sometimes be obtained on lower grade papers through the use of GCR. GCR may reduce the ability to adjust some colors.

无论i1Profiler还是ProfileMaker软件中，完成数据测量以后就必须进行分色设置来生成设备的ICC配置文件。 相比PhotoShop中手动分色，现在使用ICC配置文件大大提高的分色的效率和自动化。 所以，分色的优劣和ICC制作过程中的设定有很大的关系，以爱色丽i1Profielr色彩管理软件为例，讲解ICC制作过程的分色设定参数。 在屏幕上的图像要印刷之前，先要将其转换为CMYK模式。 图像处理软件可以很容易的将RGB转换为CMYK。 这个看上法很简单，其实要复杂得多。 CMYK …
