A method for driving a printing press, the printing press including:
- first driven means driven by first driving means;
- a first rotating body including a notch, the first rotating body being rotationally driven by the first driven means;
- second driven means rotationally driven by the first driving means through the first driven means;
- and
- a second rotating body provided with a notch at a position corresponding to the notch of the first rotating body, the second rotating body being rotationally driven by the second driven means, the method comprising the steps of:
- providing braking means to any one of the second rotating body, the second driven means, and third driven means rotationally driven by the second driven means;
- and
- obtaining a correction value according to load applied to the first driving means and correcting a braking force of the braking means according to the obtained correction value.
