In building on the successes and advances of Epson UltraChrome Ink, the Epson UltraChrome K3 Ink Set is without rival. Featuring a set of three shades of black ink - hence the K3 denominator - UltraChrome K3 colour and black and white prints display a high level of quality not previously seen from an inkjet printer. UltraChrome K3 delivers quality prints that have a depth of colour rivaling that of most commercial printing presses and silver-halide photographic prints.
