The printing part is the core of the flexographic printing machine. The arrangement of the printing part directly affects the operation performance, print quality, printing speed and the scope of application of printing. According to the arrangement of printing parts, flexographic printing presses can be divided into three types: stack type, satellite type and unit type.

The flexographic printing machine uses fluid ink with strong fluidity. The ink is transferred to the graphic and text part of the printing plate by the ink bucket rubber roller and the anilox ink transfer roller for inking, and then the printing pressure is applied by the pressure roller to transfer the ink on the printing plate to the substrate, and finally the printing process is completed through the dry surface.
