1. From the point of view of process characteristics:

There are relatively few kinds of color in screen printing, because screen printing glass can only print one color at a time. And UV printing can be printed out at one time, without the need to make another screen, just need to draw a good computer chart. At the same time, silk screen printing glass can not produce gradient color, UV printing can print brilliant, beautiful pictures, gradient color can also be printed out in one time. Finally, the adhesion of printing color, silk printing ink in silk printing will reinforce the glass surface, so that ink better adsorbed on the glass surface, do not use sharp tools to scrape gifts will not be lost, although UV printing will spray a layer of curing agent-like coating on the glass surface, but it will easily fall off, especially over time. Over time, the printed pattern will fall off layer by layer. Glass screen printing is generally used on electronic products with high requirements for screen printing. The screen printing technology used in household appliances glass can ensure that the ink will not fall off for a long time. UV printing is often used in some home glass decoration, such as moving doors and so on, to bring beautiful visual enjoyment to our home.

2. From the point of view of printing principle: UV logo printer uses piezoelectric inkjet printing, screen printing uses contact printing.

3. From the point of view of pollution degree, UV label printer belongs to environmental protection and green printing, while screen printing belongs to high pollution printing.

UV printing is a printing process that dries and solidifies ink by ultraviolet light. It is necessary to match the ink containing photosensitizer with the UV curing lamp. The application of UV printing is one of the important contents in printing industry.

Screen printing refers to screen printing with pictures and texts by using screen as the plate base and photosensitive plate making method. Screen printing consists of five elements: screen printing plate, scraper, ink, printing table and printing material. In screen printing, some of the screen holes can pass through the ink, while some of the non-screen holes can not pass through the basic principle of ink. When printing, the ink is poured into one end of screen printing plate, and the scraper is used to exert certain pressure on the ink part of screen printing plate. At the same time, the ink moves uniformly towards the other end of screen printing plate, and the scraper is squeezed from the mesh of the graphic part to the substrate during the movement.
