The offset sheet printer 2 has five printing units of the barcode printing section 310 for printing the barcode 13, the transaction detail column printing section 330 for printing the characters, the ruled lines and the like, the C printing section 351, the M printing section 353, and the Y printing section 355 for printing the color patterns 18. The first plate (the plate for the transaction detail column), the second plate (the three plates of C, M, Y for the color patterns), and the third plate (the plate for the barcode) are wound around plate cylinders 31 of the respective printing sections and printing of the respective plates are carried out. |
