Archival Storage
Keep it out of the light.
Improper storage ruins millions in value annually.
The Three Enemies
- Light (UV): The primary killer of dye-based inks. Always frame with 99% UV-filtering museum glass.
- Humidity: Causes paper to fox (brown spots) and ink to bleed. Target 45-55% relative humidity.
- Acid: Standard cardboard backing will burn paper over time. Use only acid-free, lignin-free mats and backing boards.
