An improved version of Epson's Archival ColorFast ink and developed for the latest generation of inkjet professional printers, Epson UltraChrome ink is one of the most important advances made in printing. Achieving superb color expression on a variety of media is made possible by an increase of the density of pigment content in the ink, which also provides for a much wider range of media support. Even with greater pigment density, each particle has an extremely smooth and uniform resin coating, ensuring superbly sharp image reproduction on both specialty media and plain paper along with marked improvements in light and water resistance.
