Durability: Documents printed with DURABrite Pro inks can be stored in the office without compromising their readability. An independent test showed that they can last over 400 years when kept in the dark. Reliable print quality: Unlike oil-based pigment inks, DURABrite Pro's water-based pigment ink does not cause paper to curl when documents are stored in polypropylene clear sleeves. This makes archiving easier and protects printed documents from quality loss. Water-based pigment ink: Epson's business inkjet printers use pigment inks that, unlike dye inks from conventional inkjet printers, enhance image quality and simplify document storage. Water-based pigments deliver high-quality color prints. Thanks to their high resistance to water and highlighters, these inks are versatile, suitable for business documents, direct mailings, and simple flyers. Scratch-resistant: Epson's pigment inks penetrate deep into the paper fibers, preventing document tampering.
