A favorite with photographers, graphic artists and print-for-pay providers, EPSON Premium Semigloss Photo Paper (170) is an instant-drying paper on a resin-coated (RC) base. This RC barrier allows the paper to maintain vivid, lifelike colors that rival traditional prints. Its non-cockling base make it ideal for photographs, promotional pieces, layouts, portfolio images, proofs, displays and posters. It creates high-quality prints by offering maximum ink coverage with brilliant color inks that dry in an instant. The paper can also be easily laminated to provide protection from light and moisture. Best of all, it works with both dye and pigment ink systems. Like all of Epson's innovative media, this paper is engineered to give you the highest resolution and color saturation possible. Epson's printer driver software actually optimizes the amount of ink released onto the page, based on the type of paper used. As always, EPSON supplies guarantee EPSON quality.
