Japanese paper and hinges in picture framing: an ancient method for modern conservation

In fine and conservation framing, the way an artwork is mounted is just as important as the frame that surrounds it. At Menor, traditional Japanese paper and hinge techniques are valued not for their age, but for their proven ability to protect artworks over time. These methods, rooted in centuries of Japanese conservation practice, continue to set the standard for responsible modern framing.

What is Japanese paper?

Japanese paper, commonly known as washi, is handmade using long plant fibres such as kozo (mulberry), mitsumata or gampi. Unlike many Western papers, washi is:

• Exceptionally strong despite its light weight

• Flexible, allowing it to move with changes in humidity

• Naturally acid-free and stable over time

These properties make Japanese paper ideal for conservation framing, where strength must never come at the expense of delicacy.

What are traditional Japanese hinges?

T, V and Pass Through hinges are traditional mounting methods used to attach artwork to a backing board without stress or restriction.

T-hinges are vertical hinge strips adhered to the back of the artwork with a horizontal cross strip adhered to the backing board – forming a T shape.

V-hinges are formed by two angled hinge strips that meet at a point to create a ‘V’ shape between the artwork and the backing.

Pass-through hinges use a hinge strip that passes through a slot in the backing board, with no adhesive applied to the board itself.

These traditional approaches:

• Prevents cockling or warping

• Allows natural expansion and contraction

• Ensures the artwork remains fully reversible

The glue: a process rooted in patience

Central to the effectiveness of Japanese paper hinges is the adhesive used - traditionally a wheat starch. The process of making this glue is carefully controlled:

1. Pure wheat starch is mixed with water

2. The mixture is gently heated and stirred until it forms a smooth paste

3. It is then strained and allowed to cool, producing a clean, stable adhesive

Unlike modern synthetic glues, wheat starch paste is:

• Acid-free and non-toxic

• Fully reversible with moisture

• Stable over long periods without damaging fibres

This makes it ideal for museum-grade framing and conservation work.

Why use an ancient method in modern framing?

While faster, permanent adhesives may seem convenient, they often compromise the future of the artwork. Japanese paper and T-hinges offer key advantages:

• Conservation-first mounting
  Artworks can be safely removed or re-mounted without damage.

• Material compatibility
  Natural paper and glue work in harmony with paper-based artworks.

• Longevity and trust
  These methods have been proven over centuries in archives, museums and galleries.

• Minimal visual impact
  The hinge system is hidden, allowing the focus to remain on the artwork itself.

Tradition as a foundation for quality

At Menor, Japanese paper and T-hinges are not viewed as old-fashioned techniques, but as intelligent solutions refined over time. By combining these traditional methods with contemporary framing expertise, we ensure each piece is supported, protected and respected - now and in the future.

In conservation framing, the best solution is often the one that leaves the lightest touch.
