For fine art photographers looking for a matte medium that can deliver a wide color gamut with a natural color, Epson has developed Hot Press Natural Paper. Made from 100% cotton rag and using a hot press production technique, this paper features a smooth matte finish. The heavy weight of 330 gsm, thickness of 17 mil, and opacity of 98% further give this paper the look and feel of a true fine art paper. Also, by forgoing the use of optical brightening agents, this media will offer a warmer, more natural coloration that is less prone to degradation over time. Designed for longevity, Hot Press Natural is free of acid, lignin, and chlorine and is pH buffered. Sheet/Roll Size: 13 x 19; Paper/Media Thickness (mil): 17 mil; Paper/Media Color(s): Natural; Color Family: White.
