摘要:
A method of extending the gamut of standard 4 color process printing is presented. The method thus yields various novel process printing ink sets. According to exemplary embodiments, an extended color gamut can be provided without requiring the addition of a sixth or seventh primary ink to the existing 4-color ink set. In some embodiments, an enhanced gamut can be achieved by changing the colors of the four basic primary inks and only adding a fifth primary ink. This may be done, for example, by shifting the hue of two or three of the CMY primaries and adding an additional primary. Using only five process inks thus provides, for example, the typical packaging printer with more open print stations for spot color printing or for overprint varnish application. In another illustrative embodiment, a sixth process color may be added to the inventive five color ink set.
