[China Glass Net] Process for making frosted glass jars: Draft - Screening - Printing glass etching ink - Flushing - Finished product
1. Script: Use the computer to design the desired pattern. The small format can be outputted by a laser printer, and the large format can be engraved on a black sticky note by a computer engraving machine or output by a laser phototyper.
2. Web version: Please use 100-180 mesh polyester mesh for the screen version. It is better to use monofilament polyester mesh cloth as the best.
3. Printing glass etching ink, before printing, it is necessary to remove the stain and wet of the glass surface, fully mix the frosting paste (ie screen printing ink), avoid using iron, and better use "bamboo wood" products. When printing, it is necessary to smear twice on the screen, the purpose of which is to increase the ink. For example, by hand printing, the etching ink can be scraped from one end to the other end, and then the blade is lifted to the back of the ink, and then scraped to the end of the printing. Its purpose is to increase the printing material. This means that the desired amount of ink is achieved on the glass surface. If the printing is carried out in winter, the etching ink should be heated to 20 ° C - 40 ° C for better use. Float glass must be used when using glass, and flat glass is not desirable. Because the thickness of the glass is uneven, after the hot pressing of the glass, the unevenness of the cooling makes the material structure of the glass uneven, so even after printing, the planar effect of the etching is uneven.
4. Rinse, store the first printed glass for three minutes, then rinse it in the pool or rinse it with tap water. After the water on the glass is dry, it will show a snow-like pattern. This kind of glass is very popular in the market and is loved by consumers. Using the above process, tea sets, handicrafts, gift glasses, glass containers, etc. can be produced.
