I'm sure there are a million threads regarding this (believe me, i've looked over them)

Has anyone got any registration tips at all for registering multiple screens? Especially over a large print (A1).

Obviously i use reg marks and the tip i was taught was a snapped credit card taped to form an edge to push the paper against, i can't do this anymore because it effects the screen contact and it's not quite accurate enough for a process print or any other form of 5+ colour prints.

Anyone wish to share their tips? I'd be more than grateful.
