Epson UltraChrome K3™ ink technology represents a turning point in the history of ink jet printing. Inspired by our past generations of pigmented ink development, Epson's all new 8-color ink set uniquely incorporates three levels of black, which along with new color pigments, dramatically raises the bar for professional color and black and white prints. Epson UltraChrome K3 ink can produce archival prints with amazing color fidelity, gloss level, and scratch resistance, while providing consistently stable colors that significantly outperform lesser ink technologies. This breakthrough ink technology also makes it the perfect choice for professional neutral and toned black and white prints with higher density levels and virtually no metamerism.
