Expanding the Possibilities of Color

Why CMYK won't do

The 4-color printing process known as "CMYK" requires four separations in cyan, magenta, yellow, and black to produce the corresponding printing plates. The fact that the CMYK color space is significantly smaller than the color space visible to the human eye underscores the limitations of 4-color process printing in color-critical applications like fine art and packaging. Violets, greens and oranges, for example, are very difficult to match using 4-color process. Because CMYK has a limited color gamut, it can simulate only about 60 percent of Pantone colors.
