As a rule, fine art paper and 100% cotton canvases last longest. ** Depending on material and exposure to UV. These conditions are comparable to illumination in galleries and museums, offices and living-rooms.
* Testing conditions and results according to the Wilhelm Imaging Research Institute: 25 degrees Celsius, air humidity 60% and light of 450 lux, at an exposure of 12 hours per day. Thanks to our combination of the inks, fine art paper, types of canvas and the possible varnish or scratch-resistant UV Top coating we can make Certified Art Giclées which last between 70 to 400** years. Moreover, we at Re-Art also conduct tests for lightfastness by means of the Blue Wool test, in which we expose materials to high levels of UV light. The inks, types of paper and canvas that we use have been subjected to extensive durability tests in one of the most prominent, reliable and fully independent ink–media research institutes in the world: the Wilhelm Imaging Research Institute* in Iowa in the United States. Inks and OBA-free and acid-free materials are essential for the durability.
