Said press(es) and black (one color assumed). Assuming the Leg and Back were tallied in the 1596.
My math says 1596 / 2 (presses) = 798 / 4 (hrs) = 199.5 per hour / 60 (mins) = 3.35 a min.
It's cranking and a grind, but with the mentioned dryer/catcher, sounds do-able. Providing my math and the story match.
