Arches® Watercolour paper is an acid-free, chlorine-free, 100% cotton paper, which lends the product resistance, stability, and a characteristic feel. The traditional production process on a round cylinder gives the item a varied, harmonious texture: cloth, fine, or satiny. Surface sized 'inside' and dry on the surface, the colours are rendered beautifully even after scratching and gumming. Its natural dye and anti-fungal protection ensures its excellent permanence. Recommended for watercolours, gouache, poster paint, acrylic, ink, and calligraphy. May be used on offset typography.
