2. Description of the Related Art Conventionally, a prepaid card is manufactured by printing an original fabric made of a synthetic resin and then punching the printed original fabric into individual cards by a punching machine. The original fabric is generally made of a sheet material such as polyethylene terephthalate, and the surface of the original fabric is offset-printed by a printing machine.

Therefore, the curl is removed by the curl removing device from the original sheet before entering the printing machine. Generally, the amount of curl generated in the original fabric is different, but in particular, the amount of curl in the direction (width direction) orthogonal to the transport direction greatly changes under various conditions. Therefore, it is difficult to accurately predict the curl amount and adjust the effect of the curl removing device. Conventionally, a curl is cut into the size of a product after printing and then a sampling inspection is performed to grasp the curl amount, and the curl removing device is adjusted based on the curl amount.

As described above, conventionally, after printing, the original fabric is cut into product dimensions and then the sampling inspection is performed. In this case, it takes a long time to adjust the curl removing device. Therefore, it is conceivable that a large number of defective products will be generated in the meantime.
