Which Color Gamut can be Achieved in Multicolor Printing and in Television?

The color gamut in multicolor printing is usually illustrated as hexagon in a chromaticity diagram. However, this neglects the third dimension. In this study, the color gamut is calculated as volume in a near visually uniform color space. In the first part, the color gamut of the theoretical primary colors for multicolor printing is investigated. By variation of the wavelengths of optimum colors the exact spectral values of the best suited primaries can be derived.

By variation of the wavelengths of optimum colors the exact spectral values of the best suited primaries can be derived. The second part deals with the color gamut resulting from the real primaries used in multicolor printing and television. In a comparison, the color gamut which can be achieved with all existing surface colors is calculated. It is shown that multicolor printing is able to render almost 50% of all surface colors.
