This is interesting ... I tried Papillio because of all the good things said about it, but it would not lay down smooth. I tries 3 kinds of softeners and it still wouldn't set. If it does require removal of a clear protection film, their instructions did not mention this. Maybe this is what made it seem too thick to settle over bumps. That is very odd because I had no trouble printing .. with my Epson printer. Mine is an R3000 with UltraChrome K3 pigment ink, so the ink is probably different that what was mentioned. I have been using Micro Mark paper a lot and it works very well.
