First, the origin of screen printing:

Like the movable type printing, stencil printing is recognized by the world as one of the ancient inventions in China. Screen printing is gradually developed from the pupil version. It originated from the folder printing process of the Qin and Han Dynasties and has a history of more than 2,000 years. According to archaeologists, there have been quite a number of batik products in the Eastern Han Dynasty. This kind of process has a great leap forward in the era of the modern era, that is, the Internet is stretched at the bottom of the printing, and the printing process has developed into a screen printing. In the Tang Dynasty, the dresses used in the courts were able to print fine and detailed bee-pet designs with silk screen printing. Silk screen printing, Ningbo silk screen printing ink factory

Second, the characteristics of screen printing:

The most widely used screen printing in China is the electronics industry, ceramic decal industry, and textile printing and dyeing industry. In recent years, screen printing, advertising, posters, etc. have also been widely used for screen printing.

Screen printing has the following characteristics:

1. Not limited by the size and shape of the substrate. Generally, printing can only be carried out on a flat surface, and silk screen printing can not only print on a flat surface, but also print on a special shaped molded object and a concave convex surface, and can also print various super large advertisements, drapes, curtains. It can also be printed on ultra-small, ultra-high-precision items and can also be printed on curved or spherical surfaces. This printing method offers great flexibility and wide applicability. All shapes can be printed with silk screen. Screen printing is also possible for those special shaped faces.

2, the layout of the soft printing pressure is small. The screen printing plate is soft and flexible, and has a small printing pressure. Therefore, it can be printed on soft substrates such as paper and textiles, and can be printed on glass and various glass and ceramic vessels which are easily damaged by pressure.

3, the ink layer is thick and strong. The thickness of the ink on the relief and lithographic prints is only a few microns, the gravure printing is only 12-15 microns, and the oil color of the screen printing can reach 30-100 microns. Therefore, the hiding power of the ink is particularly strong, and it can be completely black. Printed on paper in pure white. In addition, printing such as circuit boards and oil paintings can be performed using the characteristics of the ink layer thickness. Braille lettering printed with foaming ink, the thickness of the ink layer after foaming can reach 300 microns. The screen printing ink layer is thick, and the printed graphic has a strong three-dimensional effect, which is unmatched by other printing methods.

4. Suitable for all types of inks. Screen printing has the characteristics that it can be printed using any kind of paint, such as oily, water-based, synthetic resin type, powder, and the like.

5, strong light resistance. Since screen printing can print a thick ink layer, various binders and various colorants can be used, and even coarser pigments can be used, so that light-resistant pigments and fluorescent pigments can be placed in a simple manner. Into the ink, the prints of the prints will remain permanently glossy without the influence of temperature and sunlight, and even glow at night. Because silk screen products have strong light resistance, they can be used for advertising and signage outdoors.

6, flexible printing methods. Screen printing, like flat, concave, and convex printing, can be industrially produced on a large scale. At the same time, it has the advantages of flat, concave and convex printing, which is incomparable in plate making, low in price, flexible in printing method, flexible in technology and easy to grasp in technology. Therefore, it has developed rapidly in recent years. It is not limited by the size of the enterprise. Large industrial mechanization can be produced, and township enterprises and individual handicrafts can also be produced.
