A printing base material 1 such as a multi-layered paper or film, including an overlay, an adhesive material layer, and a release mount and having a total paper thickness ranging from 100 μm to 200 μm is passed through a gap between a die cut roll 7 to which a die cutting blade is removably attached and an anvil roll 8 rotating in engagement with the roll 7, and half-cutting for cutting the base material to an optional amount in the direction of thickness simultaneously with printing, full-cutting for cutting another region from the above region to the lowermost point in the direction of thickness and printing to the overlay are performed for the base material on a rotary press at the same time.
