Vive la France. Vive PURE COTTON. PURE COTTON is a 100% cotton paper produced by the Zuber Rieder paper mill in France. PURE COTTON is the perfect material for letterpress printing, embossing, hot-foil and many more classical and luxurious finishing techniques. We are also experiencing an increase in the use of PURE COTTON as the material of choice for high-end brochures and catalogues produced using offset printing.
