Joe D.You are mostly correct... that is a work-and-turn form that I mentioned earlier.
It is really how to do a job like this.
but the press doesn't rotate
Basically you print the fronts and the backs on the same side of the sheet... but the fronts are facing one direction and the backs are 180 degrees in the other direction.
After the pressman runs one side of the paper... he turns the sheet left to right and runs the paper through the press again using the same plates. Doing so... the backs correctly back up the fronts and the fronts back up the backs... and the pressman didn't have to change printing plates.
If you print out my little drawing of a press sheet - below - print two copies and make one the back of the other you will see how the fronts and backs back each other up correctly and everythign goes right side up.
