First chance to check back since last night, and agree with Alan and John (maybe I took it slightly personally, but I did edit a couple of times before posting) I do see those benefits, but they don't show up here, probably because of the way we do things (ya think?) However, we are going through a number of changes to tighten up all of our processes and systems, and will probably revisit it all again, because quality printing always comes first, and anything that improves that without denting the bottom line is what we want to do. In the end, I guess the OP will have to do the testing to see if it works for him. And for what it matters, the best printing work I've seen was by Mark Coudray, with rollers at 25N; I'm not completely sold on the appreciable advantages of the extra 5, 10 or 15 Newtons...
