Surface Finishing:
In Screen printing, a screen mesh is used as plate to transfer the ink to the targeted printing area of the paper box. Meantime, the blank area on the paper box remains blank by applying an impermeable coating on the mesh to prevent the inks from passing through. A blade or squeegee is moved across the mesh to force the ink into the small opening first, then the ink is transferred to the paper box by a momentary touch. One color is printed at a time, so several screens can be used to produce a full color printing paper box.
