What is the printing process of wine bottle screen printing machine?

Wine bottles will more or less have some trademarks and instructions printed on them. Of course, a bottle of beer worth a few dollars will not be printed directly on the bottle, but directly on the bottle. This may also be related to the recycling of beer bottles, which is more convenient for disposal. A digression has come to this point, today we are talking about the process technology printed on the wine body, the silk screen printing process and heat transfer process of wine bottles.

The silk screen printing process of the wine bottle screen printing machine is relatively simple, that is, there are holes in the picture of the screen printing screen, and the ink seeps out from the holes under the movement and pressure of the scraper. Due to the pressure of the scraper, the screen and the substrate surface contacts. Since the wine bottle has a curved surface, the jig must also be rotated during printing so that the ink can be printed on the curved surface.

Simply speaking, heat transfer printing is to make a copper plate with a designed picture, and then engrave the picture on the copper plate in different colors through an electric engraving machine. Then take the copper plate to the printing machine to print the picture on the PET film, and then transfer the picture to the product through a thermal transfer machine, which can print objects of various shapes and colors .

Compared with screen printing, thermal transfer printing can print rich and bright colors, but the three-dimensional effect is relatively poor. Silk screen printing is more costly than thermal transfer printing, but the ink is thicker, with strong adhesion and a strong three-dimensional effect. For some brand products, it is also a kind of protection of property rights.
