Canson Edition Etching Rag is a 100% cotton Fine Art paper with a smooth texture, reminiscent of the original genuine etching and printmaking papers. The paper has the purest white tone available on the market, without any Optical Brightening Agents (OBA) which are artificial brighteners that deteriorate in time. Canson Edition Etching Rag offers a high paper shade stability and a resistance to aging by using natural minerals. This museum-grade paper provides deep blacks, excellent image sharpness, optimum colour graduation and its unique slight grain makes it ideal for printing detailed work, colour photographs and exceptional black and white portraits.
