The paper slackens evenly when wet, giving artists greater control during washes and layering.

The Arches Watercolour Block – Rough 300gsm is uniquely gelatin-sized “to the core,” enhancing colour luminosity and transparency while preventing paint from penetrating too deeply into the surface. This allows for easier blending, glazing, and colour lifting, whether working wet or dry.

With a papermaking heritage dating back to 1492, Arches continues to produce some of the finest professional art papers in the world, trusted by generations of artists for lasting quality and performance.
