Canson?s Number One watercolour paper is now an integral part of the Canson Infinity Digital Fine Art & Photo Portfolio. This genuine cold-press watercolour paper is specially coated for stellar inkjet printing performance. Being both acid and OBA - free, the paper is naturally age resistant. Montval??s watercolour texture and warm white tone lend subtlety to photographic reproductions and render art reproductions accurately and beautifully, with excellent colour.
