Inkpress Matte Canvas printer paper is 100% Cotton, acid and lignin free. The bright matte finish is water resistant (required for pigment inks). Due to the high flexibility, the canvas may be stretched without cracking when framed. Waterproof Canvas Matte is designed for high quality reproduction with inkjet printers. Due to the presence of natural components in the base material, the surface characteristic may vary slightly. The uncoated backside is kept naturally brownish. (Manual feed is recommened on Most Printers)
