Oh, wow. Okay I'll look into the scanning program when I get home. I use photoshop to edit my scanned images, do you know if that has a demoiré option?

And I also noticed that the full, un-cropped version of my iceman signature had those blocks of color in it as well.

Oh well, I hope I figure this out. It's annoying.
