Pantone embraced color management by leveraging the architecture to translate RGB and CMYK files to Hexachrome. They enlarged the printable color gamut by exchanging typical process cyan, magenta, yellow, and black inks with brighter and purer CMYK inks. (Figure 2). Standard CMYK inks appear dirty when compared to the more vibrant Hexachrome CMYK. In addition to the cleaner CMYK inks, orange and green inks were added to complement the brighter CMYK colors, and to maxi- mize simulating the original Pantone spot color library. Therefore, you cannot really take advantage of the Hexachrome print process by Figure 3: Top: SWOP separation to Hexachrome proof; Bottom: Proof of correctly separated RGB to just adding orange and green Hexachrome to standard CMYK inks.
