There are two main categories of the classification of screen printing: press printing method and the time and technical level of printing according to various screen printing.
One, press printing method
1. plane screen printing machine. Generally, the scraper plate presses the plate to move horizontally, and changes the print through the plate's landing.
2. surface screen printing machine. It refers to the printing of a flat screen plate on a circular surface.
3. rotating screen printing machine. It means that through the screen plate of the cylinder, it is printed and rotated through the internal scraping plate, and the line speed of the printed material is the same.
4. electrostatic screen printing machine. Refers to the good conductivity of stainless steel wire mesh, through electrostatic between the positive and negative electrode plates made through hole plate powder department to the substrate. It belongs to press free printing.
Two, according to the appearance and technical level of all kinds of screen printing machines.
1. Manual screen printing machine. It refers to the silk screen and hinges. The printing platform is made up by manual operation.
2, semi-automatic screen printing machine. As the name implies, the time of printing is partly automatic and the rest is still done by hand.
3. Automatic screen printing machine. It refers to the automatic printing with automatic printing and lifting, transportation and drying, and the collection of collecting parts. The efficiency of the printing is greatly improved.
4, screen printing linkage machine. It is a kind of printed polychrome printing machine with high efficiency and full function.
The main features of the screen printing machine are four points.
1, screen printing can use oil, water, powder, synthetic resin emulsion type ink.
2, the layout is soft. The layout has a certain elasticity not only to print on the cloth paper, but also to be printed on the hard articles such as glass and ceramics.
3, the ink layer is thick, and the covering power is strong.
4, screen printing press force is small. Because the pressure of printing is small, it can also be printed on fragile objects.
5. It is not restricted by the size and shape of the printed matter. Not only can it be printed on small objects and can be printed on large objects. The printing method is both practical and flexible.
