    The "3" is just telling you that the reversing drum (perfector] is located in the third printing unit. So, P3 in a 4 color machine is a 2 over 2.

    They should just call it a 52-2p2. That easily reads as a 2-over-2, and there’s less confusion as to where the reversing drum actually is. And what’s a 52-4p?

    4p would be someone designating the press as a perfecting press, it wouldn't be that way on the machine's tag.
