Pantone (PMS) and CMYK are two different color systems used in printing. Pantone colors are pre-mixed, standardized colors that ensure precise and consistent color matching across all printed materials. They are ideal for branding and corporate colors that require exact replication. On the other hand, CMYK (Cyan, Magenta, Yellow, and Black) is a four-color process used to create a wide range of colors by blending different percentages of these inks. While CMYK is suitable for full-color images and gradients, it may have slight color variations between prints, whereas Pantone provides exact color consistency.
