How does Epson UltraChrome K3 with Vivid Magenta Ink achieve such a wide color gamut?

• Epson UltraChrome K3 ink uses higher-density pigments along with a higher-gloss resin encapsulation to produce prints with an extremely wide color gamut. Now enhanced with our revolutionary new Vivid Magenta pigments, our newest-generation ink technology is capable of producing (for most prints) a color gamut that is better than virtually any dye-based printer.
