Printing Mesh - the basic principle of printing

Part of the hole of the Printing Mesh plate can pass through the ink and leak to the substrate; the mesh of the rest of the printing plate is blocked, the ink cannot pass through, and a blank is formed on the substrate, and the wire mesh is used as a support body. The screen is stretched on the frame, and then the photoresist is coated on the net to form a photosensitive plate, and then the positive plate is adhered to the plate to be exposed, and exposed (developed, the portion of the plate that does not need to be inked) The cured plate is formed by light, the mesh is sealed, and the ink is not transparent during printing. The mesh of the portion of the printing plate that needs to pass the ink is not closed, and the ink is transmitted during printing to form a black mark on the substrate.

Printing Mesh features:

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 shape and a concave surface of a special shape, and can also print various super large advertisements, drapes, curtains.

2. The layout is soft and the printing pressure is small. The screen printing plate is soft and flexible, and has a small printing pressure. Therefore, it can be printed not only on a soft substrate such as paper or textiles, but also on glass (ceramic ware) which is easily damaged by pressure.

3. The ink layer has a strong covering power. The thickness of the screen-printed ink can reach 30,100μm. Therefore, the hiding power of the ink is particularly strong, and it can be printed on pure black paper.

5. Strong light resistance. The general classification of inks should be divided into printing patterns, namely, letterpress ink, lithographic ink, gravure ink and filtered ink. However, such a classification is too principled and cannot express all the realities. In recent years, due to the increasing number of inks, new types of colors have appeared continuously, and only by type, there are limitations.
