The results of the tests using Canon I950 with Canon BCI-6 series inks and various manufacturers papers. The aim of the tests is to find which paper and ink combination fades the least.
The test will run for at least 10 weeks, with reports and images weekly where possible. Each piece of paper has 2 copies of the "PhaseOne-CMS checker high resolution" printed on it. Each one will be cut in half, one half stored in a folder and the other half subjected to sunlight through a window all day. Each week both halves will meet on the scanner before going their respective ways.

Both the HP and Kodak papers claim about 100 year life. The HP one implies almost any inkjet print.
