what is cmyk color

CMYK stands for Cyan, Magenta, Yellow, and Key (Black) . It is a subtractive color model used in color printing and describes the printing process itself. The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called subtractive because inks "subtract" the colors red, green, and blue from white light; white light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. The CMYK color model is used to create full-color graphics and images in commercial printing equipment by combining varying amounts of the different color inks to produce a full spectrum of color. When designing artwork for print, it is recommended to start your design in CMYK color mode to help ensure your images and colors are accurate from the start.
