Experiment IX - UV Rays
The purpose of this experiment is to see what happens to the paper and Copic markers once they are exposed to UV Rays (aka "the sun") after long periods of time.
To setup this experiment, I placed each sample square down and used a purple, black and red Copic marker to draw three horizontal lines. I then scanned this as the starting point so I could visualize the change after it was finished. Then for a week, I set out the paper in the morning and took it in by night. Ah, yes, it did rain one and I forgot to bring it in another night so the sprinkler got it, but perhaps it added to the test. LOL Anyway, it was a good week of full sun light and the results were interesting.
The papers are identified in the Introduction and here are the results:

As you can see there are differences but let me go into the details of what I noticed. First on the right side is the original and then on the left is pasted the end results. What I had expected was that the black would fade the most and found it most interesting that it was the purple that was the most effected. Also, I was expecting that all papers would fade to some degree, however, they all seemed to behave about the same. The papers became a little more dry and brittle but basically kept their qualities.
Unfortunately, this test was completed without samples of U, V and X so it is missing from this test.
The biggest change was in the colors and I've categorized them into two groups - "ok" and "not so ok". The not so ok group includes B, C, D, E, F, G, J, L, M, N, P, Q, R and S.
For what it's worth, the papers that I would recommend, if you're so included to put something outside, would be A, H, I, K, O, T and W.
