Planchets don't have flat fields and if two of them are in the press at the same time the centers of the two planchets will not be touching and during the strike one will end up being very slightly concave and the other convex. Also the planchet will not expand out to the collar exactly evenly all the way around. Whichever planchet reaches the collar first will start spreading towards the other planchet first. When the second reaches the collar it can't toward the first because the first is already in the way. So as you go around the field edge junction it won't be smooth and even.
