Mounted artwork lasts longest when the hanging environment is controlled. The two biggest enemies are direct sunlight and high humidity.
Direct sunlight
UV exposure fades pigment and yellows paper over decades. Even archival prints rated 80+ years assume gallery-grade lighting, not bright direct sunlight.
- Hang prints out of direct sun.
- For unavoidable sunny rooms, use Conservation Clear or Museum Glass glazing in framed pieces — both block UV.
High humidity
Humidity speeds up the deterioration of paper, mount board, and adhesives. Bathrooms, kitchens with steam, and damp basements are particularly bad.
- Keep humidity in the room below ~60% relative humidity.
- Avoid hanging prints in rooms with frequent steam or condensation.
- Climate-controlled storage is ideal for archived editions not on display.
Temperature swings
Large temperature changes cause paper and mount expansion/contraction, which can crack or distort dry-mounted pieces over time. Stable room temperature is preferable.
