When a buffered paper is not acceptable, our non-buffered Renaissance Paper is the ideal liner choice. For use with albumen, cyanotype, dye transfer, color prints (chromogenic) and textiles. Renaissance Paper™ is perfect for photos, document interleaving, xerography, envelope-making and lining. The papers are made of acid and lignin-free 80lb. text weight with 25% cotton fiber, less than .0008% reducible sulfur content, and a smooth white surface. We watermark each sheet to identify the presence or absence of the buffering agent. All papers pass P.A.T. 100 per package
