Stacking flexographic printing machine, sometimes also called stacking flexographic printing machine. Independent printing units are stacked up and down, arranged at one or both ends of the main wall panel of the printing machine, or various color printing units are installed on the rack. Each printing unit is rotated by a gear mounted on the main wall panel. The stack type mimeograph can print 1-8 colors, but it is usually 6 colors.

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.
