Definition: Japanese paper, also known as Washi, is a traditional handmade paper prized for its strength, flexibility, and lightweight qualities. Its long fibers, usually derived from mulberry, mitsumata, or gampi plants, give it remarkable durability and tear resistance. In framing and conservation, Japanese paper is commonly used for hinging, repairs, and mounting because it is pH-neutral, reversible, and minimally invasive to artworks.

Characteristics

Long Fibers: Provides strength, flexibility, and resistance to tearing.
Lightweight: Adds minimal bulk when used in hinges or repairs.
Acid-Free / pH Neutral: Safe for archival and conservation applications, preventing degradation of artworks over time.
Thin but Durable: Can be layered for added strength without becoming visually intrusive.
Surface Texture: Can range from smooth to slightly textured, suitable for various artistic and conservation techniques.

Uses in Framing and Conservation

Hinging: Used to attach paper-based artworks to backing boards or mats in a reversible, archival-safe way.
Mending and Repair: Ideal for reinforcing tears, cracks, or delicate areas on paper artworks.
Book and Manuscript Conservation: Employed in repairing pages and reinforcing bindings without compromising original materials.
Overlay Protection: Can be applied as interleaving paper between artwork layers to prevent abrasion or transfer.

Best Practices

Cutting: Use sharp knives or scissors to prevent fraying of the delicate fibers.
Adhesive Selection: Pair with archival adhesives such as wheat paste, P90 tape, or reversible conservation adhesives to maintain longevity.
Layering: Layer multiple sheets if extra strength is needed, while keeping the repair thin and unobtrusive.
Moisture Control: Handle with dry hands and avoid excess moisture, which can warp paper or cause uneven adhesion.
