How does Epson UltraChrome K3 ink technology reduce gloss differential?

• Gloss differential is reduced because of the higher-gloss resin encapsulation technology and the three-level black system. UltraChrome K3 ink technology dramatically reduces the effects of gloss differential from both color and black-and-white prints on even the glossiest media, such as Epson Premium Glossy Photo Paper, without a gloss optimizer.
