Paper Museo® MAX — Archival (exceeds Library of Congress standards for permanence; ISO 1108, 9706 certified for permanence) using 100% cotton linters (tree free) and Artesian well water. Internally buffered (to prevent long term environmental acidification), and contains no optical brightening agents (OBA’s). OBA’s fade, yellow and shift color over time. They will also look yellow if the print is properly framed under UV blocking glazing since they work by absorbing UV light and fluorescing in the visible spectrum. This is a fine art watercolor rag paper with a lush feel. It is a heavy weight paper... prints on 17 x 22 in. paper are 365 gsm weight and 0.021 in. (530 µm) thick, other sizes are 250 gsm and 0.015 in. (380 µm). Technically advanced (1.66 Dmax with K3 ink; 91 brightness), it can produce exceptional blacks with a wide tonal rage and color gamut. The paper stock used for my prints was developed and distributed by Crane & Co in Dalton, MA (before they stopped distributing it and sold the license). This company has continually supplied the United States Treasury with its currency paper, the most durable in the world, since 1879. In 1770 Stephen Crane took over Massachusetts’ first paper mill.
