White aluminum sign for sublimation. These are great for a parking sign, road sign, photo print, pool rules, shop rules or anything else! They can make a great gift for any occasion! Our aluminum signs have a high quality sublimation coating on one side which will ensure your product lasts for years and years. If you are hanging your sign outside, you can give it a UV protectant spray, but I have had a sign outside in the sun for over 2 years now with minimal fading. Sub at 400F (204C) for 75 seconds at medium pressure. Make sure to remove the plastic protective layer before subbing
