The Difference Between Glass Screen Printing Process, Painted Glass And Screen Printing Glass

The difference between glass screen printing process, painted glass and screen printing glass

1. Materials required for silk screen glass production

1. Ink: Ink is necessary for silk screen printing. Without ink, where would the pattern come from? There are many colors of ink, and adjusting ink is something that screen printing masters must learn.

  2. Screen: The screen is prepared for printing patterns on glass. The stencil is first coated with photosensitive adhesive, and then combined with film and strong light, the pattern is applied to the stencil. Place the film under the stencil, and then use strong light to expose the photosensitive adhesive on the stencil. After finishing, rinse off the photosensitive adhesive blocking the part of the film, and the pattern will be created.

 3. Oven: The oven reminds us of baking. Yes, it means putting the glass in the oven to bake. After the pattern is printed on the glass, the ink on it does not dry quickly. If you pick up the glass at this time, you will touch it. Ink, this will destroy the pattern. After passing through the oven, the ink will dry and the pattern will not be easily erased.

 4. Tempering furnace: Why do you need to go through the tempering furnace? Silk screen printing is divided into high temperature screen printing ink and low temperature screen printing ink. High temperature screen printing ink must be screen printed first and then go through the tempering furnace. This way the ink is bonded to the glass surface, making it impossible to wipe it off.

 2. The difference between painted glass and silk screen glass

Different.

 Painted glass is also called back-painted glass in the industry, and is divided into flat glass paint and frosted glass paint. It is to spray paint on the back of the glass and bake it in an oven at 30-45 degrees for 8-12 hours. In many places where lacquered glass is made, natural air drying is generally used. However, the adhesion of the naturally air-dried paint surface is relatively small, and in a humid environment It is easy to fall off. The painted glass has bright colors and many colors. It has a strong decorative effect. It is mainly used for the decoration of walls and background walls, and is suitable for interior decoration in any place.

Screen printing belongs to stencil printing. Silk fabric, synthetic fiber fabric or metal mesh is stretched on the screen frame, and the screen printing plate is made by hand-engraving paint film or photochemical plate making. Modern screen printing technology uses photosensitive materials to make screen printing plates through photographic plate making (so that the screen holes in the graphic and text parts of the screen printing plate are through holes, while the screen holes in the non-graphic and text parts are blocked. live). During printing, the ink is transferred to the substrate through the mesh of the graphic part through the squeezing of the scraper, forming the same graphic and text as the original. Screen printing equipment is simple, easy to operate, easy to print and plate making, low in cost, and has strong adaptability. Screen printing has a wide range of applications. Common printed materials include: color oil paintings, posters, business cards, binding covers, product signs, printed and dyed textiles, glass, etc. Silk screen glass uses high-temperature ink to form a pattern on the glass surface through a screen printing process. After tempering or high-temperature baking, the ink and the glass surface are tightly combined. Unless the glass is broken, the pattern and the glass will not be separated.
