Superb resistance against the effects of water
Since dye-based ink contains water-soluble colorant, the colorant dissolves when coming in contact with water. With Epson's DURABrite Ultra pigment ink, every ink particle is encapsulated with a soft, yet extremely strong, protective resin. The results are prints with superb water-resistance to spills, humidity and to moisture introduced by using highlighter pens on your plain paper business documents.
