PURPOSE: A gravure printing machine which prevents the printing of ink in a non-image area is provided to improve printing quality by accurately scrapping ink from a non-image area using a second blade. CONSTITUTION: A gravure printing machine comprises a gravure plate cylinder(1), an ink supply device(12), a first blade(6) and a second blade(7). The gravure plate cylinder has multiple grooves(2) on the circumferential surface. An ink(3) is charged in multiple grooves in order to form the image area. The ink supply device supplies the ink to the circumferential surface of the gravure plate cylinder. The first blade contacts with the circumferential surface of the gravure plate cylinder in a contact angle, less 45°. The second blade contacts to the circumferential surface of the gravure plate cylinder in contact angle higher than 45°.
