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.
