An improved version of Epson's Archival ColorFast ink from InkTec Inks. developed for the latest generation of inkjet professional printers, Epson UltraChrome ink has been 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.
These pictures show an enlarged cross-sectional image of printing - Ideal light reflection broadens the range of color reproduction.

Epson UltraChrome Ink can deliver twice the density of conventional Epson pigment ink. As a result, it reproduces a larger range of color compared with traditional silver halide photographs.

Superb water resistant Epson pigment ink

(Ultrachrome on the left and Dye Based Ink on the right - Both on Plain Paper)
Dye based inks contain water-soluble colorant, therefore the colorant dissolves when coming in contact with water.

The pigment colorant improves light and gas resistance. Since the pigment colorant exists in the particle form, only the surface is affected by light and gas, and the color inside remains vivid. Epson UltraChrome Ink utilises this property of pigment ink effectively achieving superior light and gas resistance.

PLEASE NOTE:-
You can switch your printer back to using regular inks at any time. However, it is not practical to switch back and forth. If you are setting up a Ultrachrome Printing System you should not expect to use the same printer for other purposes.
