I'm not sure about triethanolamine... doesn't ring any bells, but I don't have that many. . . (bells that is)

Thanks PE, I will definitely check that out. You say like sized nails, but I'm not sure if there are nails equal in size to the diameter of an office punch, which is about 6mm.

Visual registration, as easy as it sounds on paper, I think it would be diffucult; definitely an art. Have you ever done it? I know that it is not easy or fun with my screen-plate stuff, but those tolerances might be far less forgiving.

Going to the "dark side" to do a respectable test with Kodak magenta... will advise.
