CMYK, which stands for Cyan, Magenta, Yellow, and Key (Black), represents the primary colours used in the printing process. Printing presses employ tiny dots of ink in these four colours to create the complete image.
The term “Key” refers to black, denoting its significance in determining the final image. Black ink is responsible for creating depth and shading, while the other colours, when combined, produce a wide range of hues on the colour spectrum. For example, overlapping cyan and yellow inks result in the creation of green.
