What is the meaning of cmyk?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black), which are the four colors used in color printing. This color model is based on the subtractive color mixing process, where colors are created by subtracting varying percentages of light absorbed by inks. CMYK is commonly used in the printing industry because it allows for a wide range of colors and is effective for producing high-quality images on paper.
