Four-color printing, also known as full-color printing or process printing, is a printing technique that uses four basic colors (cyan, magenta, yellow, and black) to produce a wide range of colors and shades in printed materials. In Chinese, "四色印刷" (sì sè yìn shuā) can be translated as "four-color printing" in English. This type of printing is commonly used in the production of books, magazines, brochures, and other types of printed materials that require high-quality color reproduction.
