Abstract: A printing apparatus includes a printing cylinder (17) that holds and transfers a sheet (4), a supply-side transfer cylinder (16 (sheet supply unit)) that supplies the sheet (4) to the printing cylinder (17) at a supply position (P1), and first to fourth inkjet heads (27-30). The printing apparatus includes a transfer mechanism (18) that receives the sheet (4) after printing at a receiving position (P2) and transfers the sheet (4) to one of a discharge route (44) and a reversing route (42). The reversing route (42) employs an arrangement that returns the reversed sheet (4) to the printing cylinder (17) at a return position (P3) located on the downstream side of the receiving position (P2) in the transfer direction of the sheet (4) and on the upstream side of the supply position (P1) in the transfer direction of the sheet (4).

Abstract: A printing cylinder includes a plurality of suction chambers and a masking sheet configured to cover the suction chambers. The masking sheet includes a non-sucking portion which protrudes from the boundary of the suction chambers toward the inside of the suction chambers. A number of through holes are formed in a portion except for the non-sucking portion in the masking sheet. The non-sucking portion exists between the sheet to be printed and the boundary of the suction chamber to be used and the suction chamber not to be used. This can prevent an ink mist from adhering to the printing cylinder.
