YMCK Pantone

One such use is standardizing colors in the CMYK process. The CMYK process is a method of printing color by using four inks—cyan, magenta, yellow, and black. The vast majority of the world's printed material is produced using the CMYK process, and there is a special subset of Pantone colors that can be reproduced using CMYK. Those that are possible to simulate through the CMYK process are labeled as such within the company's guides.
