This will work very well on smooth papers like Platine, Fabriano Artistico HP, COT 320, etc. It's a little dicey on a textured paper like Rives BFK because it will pull up fibers if you press it down too hard. The white tape was the best for textured papers. I think there is a newer version of the white tape, but I can't find it with a quick Googling.
Kerik...I find that the blue tape transmits UV when printing in the sun...
