         A working cycle of the Flat Screen Printing Machine is: feeding → positioning → setting down → lowering to the ink plate, raising back to the ink plate → scraping stroke → raising to the ink plate → lowering back to the ink plate → raising the plate → returning ink stroke → canceling Locate → Receive.

  　　 1. The power is transmitted through the transmission mechanism, so that the squeegee squeezes the ink and the screen printing plate in motion, so that the screen printing plate and the substrate form an impression line.

  1. Because the screen has tension N1 and N2, it produces force F2 on the squeegee, and the resilience makes the screen printing plate not contact the substrate except for the impression line, and the squeezing force F1 of the ink on the squeegee Down, through the mesh, from the moving embossing line to the substrate.

  　　3. After the one-way printing is completed, the squeegee is separated from the substrate together with the screen printing plate, and at the same time, it returns to the ink to complete a printing cycle.

  1. The distance between the upper surface of the substrate and the reverse side of the screen printing plate after Stenter re-inks is called the same-page distance or screen distance, which should generally be 2~5mm. In manual printing, the technique and proficiency of the operator directly affects the formation of the impression line.
