Well-preserved art retains its value better. Ensure your purchase against accidents, especially water damage. Keep a copy of your Certificate of Authenticity with your insurance company or contact me for a re-issue.
Your giclée print has been printed with archival inks on archival or museum quality papers and will last a lifetime if you care for it. After all, your Danie Bester print is a collectable art piece and will be kept for generations to come. However, even with archival prints, you should hang your print away from areas where airborne grime, dust and pollutants such as cigarette smoke can leave a discolouring residue. Most importantly, avoid long-term exposure to bright and direct sunlight as it will accelerate the natural ageing process. Some artificial lights like fluorescent and CFL energy-saving bulbs transmit a lot of UV light, which can also affect longevity.
Furthermore, avoid extreme fluctuations in moisture and temperature. Excessive fluctuations between dryness and humidity, or extreme heat and cold, can negatively affect the state of your print. If the humidity is too high, be on the lookout for mould.
