Many beautiful patterns and printed stickers are everywhere on many plastics, glass, ceramics, metals and other products. These patterns are made by something called a screen printing machine, so what is a screen printing machine? What are its classifications and characteristics?
Screen printing machines can be divided into two major categories. First, the first type can be divided into four types according to the printing plate form. The four types are letterpress, lithographic, gravure, and screen printing machines, while the other type is based on the installed plate and the imprinting structure. It can be divided into three types, which can be divided into flat press type, round flat type and round press round type printing machine.
The characteristics of screen printing machine are as follows:
First, the screen printing machine has its own unique frequency conversion speed regulation device, the printing speed can be adjusted, from 20 to 70 times per minute.
Second, the screen printing machine itself has an electronic counter. This electronic counter can automatically shut down according to the pre-designed total number, saving a lot of manpower and financial resources.
Third, the screen printing machine is very accurate in point and color, because it is equipped with a multi-color printing electro-eye device, which can improve the quality of printing.
Fourth, large-area background colors, outline dots and fine-character patterns are suitable for making with screen printing machines, because the high quality of screen printing machines can not only make the patterns clear, bright in color, but also not easy to fade.
Fifth, the pattern printed by the screen printer is bright in color, and the pattern is clear because the ink adhesion of the screen printer is very good, and the ink layer is relatively thick, so the pattern is not easy to fade.
Sixth, the screen printing machine can not only be used alone, but also can be connected to the UV dryer, or slitting machine, rewinding machine and other auxiliary machines.
Seventh, because of the high-quality configuration of the screen printer, there are also considerable savings in consumables.
Screen printing consists of five elements:
Screen printing plates, scraping scrapers, inks, printing stations and substrates.
The basic principle of screen printing is to use the basic principle that the screen part of the screen printing plate penetrates the ink and the non-graphic part of the screen does not penetrate the ink. Ink is poured on one end of the screen printing plate during printing, and a certain pressure is applied to the ink portion on the screen printing plate with a squeegee while moving toward the other end of the screen printing plate. The ink is squeezed by the scraper from the mesh in the graphic part to the substrate while moving. Due to the viscous effect of the ink, the imprint is fixed within a certain range. During the printing process, the squeegee is always in line contact with the screen plate and the substrate. The contact line moves with the movement of the squeegee. Because the screen plate and the substrate Maintain a certain gap between them, so that the screen plate during printing generates a reaction force against the scraper through its own tension. This reaction force is called the rebound force. Due to the resilience, the screen printing plate and the substrate are only in mobile line contact, while the other parts of the screen printing plate are in a detached state from the substrate. The ink and the screen are broken, which guarantees the dimensional accuracy of the printing and avoids smearing the substrate. When the squeegee is scraped across the entire plate, it is lifted, and the screen printing plate is also lifted, and the ink is gently scraped back to the original position. This is a printing trip.
