摘要

A printing machine includes: a frame; a flat anilox plate that is fixed to and located on the frame and has a plurality of cells on an upper surface of the anilox plate; an ink supplying tool that supplies the ink onto the upper surface of the anilox plate; a surface plate that is fixed to and located on the frame and on which the substrate is placed; and a printing cylinder that is arranged above the frame and is capable of moving above the frame. The printing cylinder has a flexographic plate. The flexographic plate contacts the upper surface of the anilox plate, receives the ink, and transfers the ink onto the substrate. The flexographic plate is made of an elastic material. The viscosity of the ink is in a range of 51 cP to 200 cP (ink temperature: 23° C.) at the shear rate of the ink is 100/second.
