CMYK is made up of 4 main colours that are used inside the ink plates for specialized printing processes, these colours are Cyan, Magenta, Yellow & Black. Each of the colour has its own printing plates that are used in printing press to create the wanted outcome / image. When more colours are mixed, it creates darker shadows / colours in the image.
CMYK is preffered to be used while designing a project that will be printed. CMYK determines how much ink a printer will use when printing and in what quantity for each specific colour.
