Thanks, everyone, for your speedy replies.

I was in fact inquiring about possible discoloration from the chemicals, not from the light, though it seems that thereís nothing to worry about on that account. Also, though I like the roll solution, unfortunately thatís not an option with the paper Iím using. Iíll pick up some of the 20Ē x 24Ē paper and give it a try.
