UltraChrome Ink 220ml Yellow C13T544400 for use on Epson Stylus Pro 4000/7600/9600. Epson UltraChrome ink achieves superb color results on a variety of media and this is made possible by an increase of the density of pigment content in the ink. With greater pigment density, each particle has an extremely smooth and uniform resin coating, ensuring superbly sharp image images on both specialty media and plain paper along with marked improvements in light and water resistance.
