So what process are screen printing signs made of?

In order to achieve silk-screen signs that are not easy to fall off and fade, then we should do some simple treatment on the metal surface before we print on the metal.

The first is degreasing treatment, which removes the ink on the metal surface, which can increase the adhesion of the ink, increase the firmness, enhance the resistance to friction and fatigue, and make the printed ink not easy to fade.

The next step is to remove the oxide film. Since the metal is easy to form some oxide film after contacting the air, and the oxide film is easy to react with acid and alkali, resulting in poor ink adhesion, so before printing, use sulfuric acid or hydrochloric acid to prepare a dilute solution in advance. When coated on the surface of metal oxide layer, it is easy to make the oxide layer fall off and enhance the adhesion of ink printing.

After doing this, you can select a clean metal material and perform the following steps in sequence:

Preparation materials – manuscript typesetting – film output – printing – automatic product forming – full manual product forming – full inspection – packaging and transportation

Finally, a silk screen sign is completed.
