CMYK:

Four-color printing mode is a color registration mode used in color printing. Based on the principle of mixing pigment and black ink, four colors are mixed and superimposed to form the so-called "full color printing". The four standard colors are:

C: cyan =? Cyan is also called' sky blue' or' blue'. M: magenta =? Magenta, also called' Magenta'. Y: yellow = yellow. K: K: Keyboard (black) = Registration color (black).

The reason for adding black:

Cyan, magenta and yellow are also the three primary colors of art. Theoretically, three colors can be mixed into black, but in reality, due to the limitation of production process, the purity of ink is often unsatisfactory, and the mixed black is not rich enough, so it can only be mixed with purified black. In addition, it can also save ink consumption. If there is no black ink, the black part of the picture will be mixed with the same amount of CMY to make black. If there is black, you can use black directly to reduce the amount of ink used.
