Since dyebased ink contains watersoluble colorant, the colorant dissolves and smudges when coming in contact with water. With the Epson Stylus CX5700F's Epson DURABrite Ultra pigment ink, every ink particle is encapsulated with a soft yet extremely strong a protective resin. The results are prints with superb waterresistance to spills, humidity, and the moisture introduced by using highlighter pens and daily handling.
