Arches Watercolor Paper Block Cold Press 9 in x 12 in - Durable 140 lb

Our review of the Arches Watercolor Paper Block, Cold Press, 9 in x 12 in, finds it best suited to serious watercolorists who want a reliable, archival sheet that handles washes without constant stretching. The single biggest reason to buy is the paper's 100% cotton construction and exclusive gelatin sizing to the core, which combine to preserve pigment transparency and make lifting or blending far easier than on lesser papers. This block style glued on all sides also removes the need to tape or pre-stretch sheets for many applications.

Key Features

• 100% Cotton: Long fibers provide a rich texture and durable surface that resists scratching and erasing while maintaining a pleasant tactile feel for detailed work.
• Gelatin Sizing to the Core: Sizing throughout the sheet keeps pigments on the surface for enhanced color luster and simpler blending, overlay and paint removal.
• Cold Press Texture: The moderately textured surface retains granulation and subtle brushwork while offering a balance between detail and absorbency.
• Glued Block Format: Glued on all sides with a protective cover sheet, the block preserves paper integrity and reduces the need for stretching before painting.
• Superior Strength: Cylinder mold fiber distribution yields consistent slackening when wet, giving the artist better control over washes without tearing or linting.
• pH Neutral, No Optical Brighteners: The archival quality helps work remain true over time without unexpected color shifts from brightening agents.

Who It's For

The Arches cold press block is aimed at dedicated watercolor artists, illustrators and students who value archival materials and predictable performance. Its 100% cotton construction and sizing make it a strong choice for wet techniques, layering and lifting, and for pieces intended to last.
