Archival Print Preservation: Acid-Free 100% Cotton Rag, Matting & Museum Glass Standards

Preserving fine art photographic prints requires strict museum-grade materials and non-destructive archival framing techniques that shield emulsions from acid degradation.

1. Museum Archival Framing Invariants

• 100% Cotton Rag Matboards: Acid-free and lignin-free boards buffered with 2–3% calcium carbonate to neutralize ambient air pollutants.
• Reversible Japanese Paper Hinges: Prints must be mounted using high-grade Kozo paper and cooked wheat starch paste—never pressure-sensitive adhesive tapes.
• Museum Glass (99% UV Filtration): Optical anti-reflective coating blocking 99% of ultraviolet wavelengths that cause silver photo-oxidation.
• Air Gap Spacers: The print surface must never touch framing glass, preventing moisture condensation and emulsion sticking.
