However, as soon as we try to take the image created by light and put it on paper, we enter the realm of CMYK. Cyan, magenta, yellow and black are the colors of ink we use to try to reproduce the colors we see in nature. No matter which printer you use, you are going to need ink, dye, toner, or some physical manifestation of these colors. The ingredients used in the recipe limit accuracy in the creation of a color, so there will always be a difference between what you see on your monitor and what prints out.
