CMYK颜色模型，也称为印刷色，在20世纪初首次普及。经过1800年代的广泛实验，发现青色，品红色和黄色墨水在印刷媒体中提供了最大可能的独特颜色集。黑色墨水（k代表key）也被添加到混合物中，因为无法使用其他三种墨水准确再现。
计算机或手机显示器可以再现人眼感知到的任何颜色。但是打印机只有四种颜色的墨水，因此其功能有限。在显示器上，布局可能看起来完美无瑕，但打印后图像的颜色会变得失真。 CMYK颜色模型则可以解决这些问题。它模拟了打印设备的技术能力和在显示器上混合颜色的功能，对从事广告、印刷厂和出版社工作的专业人士很重要。
与用于屏幕和数字显示技术的RGB颜色不同，CMYK颜色是专为印刷材料创建的。RGB颜色有三个通道，分别用于红色、绿色和蓝色，而CMYK颜色有四个通道，分别表示青色、品红色、黄色和关键色（黑色）。
这些通道中的每一个的测量范围为0%到100%，并将告诉打印机所需的每种墨水的相对密度。有助于根据渲染选择颜色进行打印。
