A multi-functional printing unit is provided to expand range of print selection and to print various prints using one printing unit by selecting between a printing without offset and a printing with offset by a user. A multi-functional printing unit includes an ink tank(20) filled with ink(10). A gravure roll(200) is moved by a moving device and rotates while drowning one side in the ink tank and includes a desired pattern on surface. A first press roll(300) rotates contacting the moving gravure roll selectively and presses a printing object(2) to the gravure roll moving between the gravure roll. An offset roll(400) rotates contacting the moving gravure roll selectively and prints a plastic ink transferred from the gravure roll to the print object. A second press roll(500) rotates by being moved through the moving device and by being in contact with the offset rolls selectively and presses the print object to a side of the offset roll moving between the offset rolls.
