Representing our next generation of photographic ink technology, the all-new nine-color Epson UltraChrome HD ink set resets the standard for photographic imaging excellence. Utilizing newly developed core pigments — including a new Photo Black pigment 1.5 times denser than our previous generation — the level of photographic clarity, optical density, and vibrancy represents a new benchmark for Epson. Individual 25.9 ml ink cartridges offer even greater productivity.
