Since 1492, the ARCHES paper mill has been making papers with unchanging qualities. Made on a cylinder mould, ARCHES Watercolour paper has a harmonious natural grain. Thanks to this method, the fibres are evenly distributed, the paper slackens uniformly when wet. Its composition with long fibres of 100% cotton gives the paper its strength, beauty, a natural, lasting whiteness and an inimitable touch. ARCHES is the only paper mill in the world to gelatin size its watercolour paper (to the core). This preserves the lustre and transparancy of the colours whilst preventing paints from penetrating the paper. It allows superposing of washes and gives it added strength to resist erasing and scratching without tearing or linting. It also allows paints to be removed, either wet or dry, easily revealing the whiteness of the paper. ARCHES Watercolour paper can absorb a large amount water with limited deformation. Acid and OBA-free, ARCHES Watercolour paper will stand the test of time. It is particularly recommended for all the wet techniques: watercolour, goache, ink, acrylic.
