A preset controller of a compensator in a rotary press is provided. The rotary press includes a compensator for use in a paper leading course extending from a printing unit to a folding unit and a movement device for moving the compensator, and controls the movement device so that the compensator is moved to a preset location suitable for cutting a printed web at an optimum position thereof.
