Designed for fine art printing, this 44" x 49' roll of GALERIE Prestige Gold Cotton Smooth Paper from Ilford features a smooth matte mould-made 100% cotton rag base that is optimized for use with pigment-based inks. The heavy paper has a basis weight of 330 gsm for ensuring prints will not sag when hung for a long duration and it has a thickness of 21.5 mil. Also, it has an opacity of 100% to prevent bleed-through. Longevity is a concern with fine art prints, so this paper does not use any optical brightening agents.
