《CMYK是什么意思 CMYK和RGB的区别》,另外还附带了CMYK色值表/CMYK颜色表,希望对您有所帮助。
CMYK是什么意思?
CMYK是印刷四原色,CMYK也称作印刷色彩模式,顾名思义就是用来印刷的。CMY是3种印刷油墨名称的首字母:C:青色(Cyan)、M:品红色(Magenta)、Y:黄色(Yellow)。而K取的是black最后一个字母,之所以不取首字母,是为了避免与蓝色(Blue)混淆。从理论上来说,只需要CMY三种油墨就足够了,它们三个加在一起就应该得到黑色。但是由于目前制造工艺还不能造出高纯度的油墨,CMY相加的结果实际是一种暗红色。所以CMYK被称为印刷四原色。
CMYK和RGB的区别:
RGB就是电脑上用的,色度学上用来研究用的,就是红绿蓝,取值0~255,这没什么好说的,CMY是印刷工业用的,C:青 M:紫 Y:黄
它与RGB的换算关系:
C1=255-R
M1=255-G
Y1=255-B
因为工业颜料都不是理想的,所以无法形成真正的黑色,实践过程中要加入黑色也就形成了CMYK系统,它与CMY的关系是
K=min(C1,M1,Y1);
C=C1-K
M=M1-K
Y=Y1-K
简单说,RGB是光色,就是说光源通过这三种色来形成不同的颜色,而CMYK正好相反,它是通过反射来表现颜色的,所以它与RGB成补色关系。

几个常用CMYK值:
印刷可以用单黑和纯黑:
纯黑/单黑:C=0 M=0 Y=0 K=100
如果喷绘需要用混合黑:
大黑/混合黑:C=50 M=50 Y=50 K=100
其他:
大红:C=0 M=100 Y=100 K=0
咖啡色:C=0 M=80 Y=80 K=50
剩下的查CMYK色值表吧。
