A synchronous single/double-sided digital inkjet printer comprises a rack, feeding rollers (2, 23), take-up rollers (3, 22), two groups of inkjet printing carriages (9, 16) and driving rollers (5, 20). The two groups of inkjet printing carriages (9, 16) respectively make reciprocating motion on the two groups of track beams (10, 15) mounted on the rack, and are provided with print heads (8, 17). The lower parts of the two groups of inkjet printing carriages (9, 16) are provided with inkjet printing platforms (7, 19) mounted on the rack, and the lower parts of the two inkjet printing carriages (9, 16) are provided with the driving rollers (5, 20). The two driving rollers (5, 20) are driven to rotate in the opposite direction respectively by two independent driving devices mounted on the rack. A printing material winding method is applied to the inkjet printer. The inkjet printer and the method can not only accurately print on two sides synchronously, but also perform a single-sided printing on two pieces of printing materials by the same printer at the same time, thus realizing multi purposes by one machine. |
