What’s the difference between RGB and CMYK?
RGB (Red Green Blue) is a display color mode, used to create every other tone that is visible on your computer monitors and television screens. While each screen is capable of displaying a wide range of colors, there are still inconsistencies between screens. CMYK (Cyan Magenta Yellow Black) is a printing color mode, used for traditional offset and digital printing. The four colors (CMYK) are combined to create the color spectrum used in printing. CMYK printing does not reproduce color the same way that you view color on your RGB monitor.
