PURPOSE: A gravure printing device is provided to correct a pattern printed state on a real time basis and correct the same by increasing a recognition rate of a reference line printed on the printing sheet through a reference line cell of a continuous line shape formed in each gravure roll, thereby improving the accuracy of overlapping patterns on the printing sheet. CONSTITUTION: A gravure printing device comprises a gravure roll(20), a driving unit(30), a supporting roll(40), a sensing member, and a control unit. The driving unit supports both ends of the gravure roll and rotates. The supporting roll is arranged to be faced the gravure roll by a medium of a printing sheet and supports the printing sheet. The sensing member is formed in one side of the supporting roll, thereby sensing an align mark and a reference line. The control unit controls the gravure roll according to errors of the align mark and the reference line sensed by the sensing unit. |
