SPECIFICALLY DESIGNED FOR BUSINESS PRINTINGDesigned for business printing, Epson's DURABrite Ultra Inks are quick drying, long lasting and smudge resistant.With its resin coated pigment particles, that adhere to the surface of the paper, as opposed to sinking into it as dye-based inks do, DURABrite Ultra Ink produces fast dying, laser-like text and graphics on multiple paper types and grades.FAST DRYING AND IDEAL FOR DUPLEX PRINTINGBecause DURABrite Ultra Ink dries instantly it's ideal for use in environments where duplex printing is regularly used or set as standard. Its surface adhesion means that there is less 'bleed through' on the page and because it dries instantly there is no risk of smudging when printing on both sides of the paper.SMUDGE AND HIGHLIGHTER RESISTANTCoated in resin, DURABrite Ultra Ink particles are protected from water and highlighter pens, ensuring that they don't smudge when pages are written over or highlighted.
