To reduce the occurrence rate of bending defective products by surely correcting bend of a sheet-like PS plate.

The PS plate processing equipment is provided with an off-line bend correction device 30. The bend correction device 30 is provided with a transport driving roll 32 and a pressure roll 33 rotated in contact with and opposite to each other. The sheet-like SP plate 23d is held and transported by the transport driving roll 32 and the pressure roll 33, thereby correcting bend of the sheet-like PS plate 23d. The diameter of the transport driving roll 32 is 180 mm, and the diameter of the pressure roller 33 is 60 mm. The rubber hardness of the peripheral surface of the transport driving roll 32 is 25° and the rubber hardness of the peripheral surface of the pressure roll 33 is 65°. The pressure roll 33 is provided with a pressing amount control part 34 to thereby control the pressing amount to the transport driving roll 32 depending on the bending degree of the sheet-like PS plate 23d.
