24 color color matching

Quick answer：

The term '24 color color matching' refers to a color matching system used in the printing industry, specifically in four-color process printing (CMYK). This system uses four different colors—Cyan, Magenta, Yellow, and Key (Black)—to create a wide range of colors. Each color is mixed in various proportions to produce the desired color. This method is used to ensure accurate color reproduction across different printing processes.
