The manufacturing process of Silk screen printing glass

Why the Silk screen printing workshop is separated with other workshops? Because the Silk screen printing workshop must be very clean. The Silk screen printing workshop also called dust free printing workshop. It has manual screen printing and machine screen printing. At here, we will talk about the manual screen printing. What should be prepared for manual screen printing? And what’s the process for it?

1. Printing ink: The printing ink is essential for screen printing. And the printing ink has many colors, so the printing master must learn printing ink mixing.

2. The screen plate: The screen plate is prepared for printing patterns. First wipe the photoresist on the screen plate, then combine with film, strong light to put the patterns on the screen plate. Put the film under the screen plate, then use the strong light again to exposed the photoresist on the screen plate, after finished, wash the film and block part of photoresist, then the patterns come out.

3. Oven: Oven makes us think about the baking. Correct, just put the glass into the oven to bake. After printing the patterns on the glass, the printing ink doesn’t dry quickly, if we take the glass at this time, will touch the printing ink and damage the patterns. After heat in the oven, the printing ink will dry and not easy to erase.

4. Tempering furnaces: Why need to put in Tempering furnaces? The screen printing has high temperature screen printing ink and low temperature screen printing ink. The high temperature screen printing ink must printing first, then go through the tempering furnaces. So that the printing ink blend together with glass surface and it’s impossible to erase the printing ink.
