Bright daylight and even artificial lighting can cause colours to fade and paper stocks to dry out. If artworks are exposed to a lot of light, try rotating them to give them a rest.
Be sure to keep an eye on the humidity. If it gets too high artworks can be damaged by damp and mould. If the humidity gets too low, print paper stock can dry out and become brittle. If the humidity swings from high to low, artworks can buckle.
Always use a professional when framing. It might costs a little more but the results are worth it. Ensure they use appropriate archival materials. Never glue or tape directly onto the backing. And don’t allow glass or perspex to be in contact with the artwork.
Take special care when transporting artwork. Ensure suitable protection between layers of artwork. Use acid free tissue paper and thick card to protect unframed prints. Make sure you have corrugated card and/or bubble wrap protecting paintings and framed prints.
Store artwork in a clean, dry area protected from the elements, insects and vermin. Protect surfaces with non-acidic material rather than cardboard or wood. And ensure your artwork is safe from bumps and knocks.
