Are you talking web presses? I can't even imagine how noisy one of those would be. I think cutsheet offset presses are awfully dang loud to start with...
I don't think I've ever seen any video where an interview was successfully accomplished in a room that loud. An extremely directional mic would be preferable (perhaps a shotgun?) Either that, or get a lot of B-roll shots of your pressroom and then interview a plant manager just outside the pressroom where you can still get a good amount of the press' noise. Then over the course of the interview, throw in the B-roll shots.
