Glass products are beautiful and cheap, but they are very challenging to print because they are hard, smooth and fragile. In order to achieve the decorative and functional properties of glass through glass printing, various companies have studied several methods to print things directly on glass.
glass picture prints /printing on glass bottles on using one of the three techniques: screen printing(silk screen printing on glass bottles), digital printing, or frit printing. These techniques can be done by glass printing machines. Silk screen printing technology is currently the most widely used, and it can achieve high-quality and accurate printing. The ink is leaked onto the glass surface through screen printing technology (the printing knife scrapes the ink off the screen), and the pattern is baked in an oven to make it firm. The silk screen printing machine is mainly composed of a screen, a scraper, a printing body, a humor system and a supporting structure, and each part coordinates with each other to complete the printing.
Digital printing is a printing technology that realizes printing by directly transmitting digital images or text information to the printing equipment. It mainly includes inkjet printing and laser printing. This type of printing equipment prints clearly and quickly, but it is expensive and the glass is prone to cracking; glass hot melt printing is to print the printed pattern in the hot melt ink cartridge, spray the ink in the hot melt ink cartridge onto the glass through the contact head, and finally dry it at high temperature to form the printing effect. This technology is highly efficient and pollution-free. But the cost is also high.
In summary, it is completely feasible to print things directly on glass, and there are many technologies to choose from. If you are interested in glass printing machines, welcome to visit.
