Sunset Copperplate Rag 315gsm is a mould-made paper, manufactured for digital printing that simulates a handmade paper. The soft grain, 100% cotton base has a matte finish with the look and feel of a true art paper. The interlocking fibers add to the art paper feel and increase durability, as well. This paper is free of optical brighteners, and is also acid- and lignin-free. The natural white base produces excellent color gamut and unsurpassed Dmax at a price point that's highly competitive with other fine art, mould-made papers on the market.
