|Epson UltraChrome K3 : This new inkset offers permanence unmatched by any other. The pigmented set has the widest color gamut available, and the ink challenges the properties of most dye-based inks. UltraChrome K3 is used with our Epson 11880 and Epson 9800 printers. ||Stability : Ink manufacturer's will claim certain levels of expectations for permanence of their inks. We consult an independent group for our data, Wilhelm Imaging Research @ www.wilhelm-research.com.
Longevity : Prints will be stable for years of enjoyment if you display them and store them properly. In general, keep them out of direct sunlight and behind display glass as much as possible.
