Urth™ is the world’s first solvent canvas with archival certification. It is a 400gsm white poly-cotton blend matte canvas. Specifically designed for the high-end fineart and photography markets, this canvas utilizes our "Chromata White" optical brightener additive-free and Fluorescent Whitening agent-free breakthrough technology.  "Chromata White" gives the end-user the most stable platform on which to print photographs and fine art works without the metamerism issues or color shift issues inherent on other canvases. Optical Brighteners compromise the attainment of true color, they complicate profiling accuracy, and they inevitably deteriorate and yellow over time.
