Colored ink does not have every color for printing paper; it typically comes in a limited range of colors. The standard set of colors used in printing, known as CMYK, consists of Cyan, Magenta, Yellow, and Key (Black). By combining different proportions of these four ink colors, a wide range of colors can be produced. However, not every color in the visible spectrum can be accurately replicated using this limited ink set. For more precise color reproduction, additional spot colors or special inks may be used in certain printing processes.
