I have in mind a project that will use black paper, but the paper needs to fold easily and not fade if left in sunlight. To find a paper with both of those qualities isn’t as easy as it sounds. I did have one black paper that was labeled as fadeproof… but it cracked online pharmacy when it was folded, and that just won’t do. So now I have to figure out whether any of my black papers that do fold well are also fadeproof. That means it’s time for a fade test.
A fade test is a test designed to see whether the color of something will fade over time. I was first introduced to fade tests many years ago when I was taking classes in calligraphy and was shown how to test inks for fading. I always want to be sure the ink and any other materials I use to make a finished work of art will last.
For ink fade tests I write with a variety of inks on a piece of paper, then cut the paper in half. I put one half in a south facing window (lots of sunlight) and the other half in an envelope in a drawer, hidden from sunlight. After about 6 months, I compare the two halves. Some inks fade, some have color shifts and I once had an ink completely disappear in just 6 months of being in the sun.
I have also used fade tests to check printer ink and watercolors. Now I get to check black paper.
I’ll report back later and post the results. In about 6 months. 😉
