Some expertise in the screen printing mesh itself

When the screen printing screen is printed, the extrusion of the squeegee causes the ink to pass through the screen hole of the graphic portion as a through hole.

Screen printing meshs are more resistant to light. This is not available in other print media. The three printing methods, such as strong printing, embossing and gravure printing, can only be printed on a flat substrate. Screen printing can be printed not only on a flat surface, but also on substrates with curved, spherical and concave surfaces.

Screen printing is to stretch silk fabric, synthetic fiber fabric or metal mesh on the frame, and make screen printing by hand-painting or photochemical plate making. The modern screen printing technology uses a photosensitive material to make a screen printing plate by photolithography (so that the screen hole of the graphic portion on the screen printing plate is a through hole, and the mesh hole of the non-image portion is blocked. live). During printing, the ink is transferred to the substrate through the mesh of the graphic portion by the extrusion of the squeegee to form the same graphic as the original. The screen printing equipment is simple, easy to operate, simple in printing and plate making, low in cost, and strong in adaptability. Screen printing applications are widely used in common prints: color oil paintings, posters, business cards, binding covers, merchandise signs, and printing and dyeing textiles.

Screen printing meshs are composed of five major elements. Due to the viscous action of the ink, the print is fixed within a certain range, and the squeegee is always in line contact with the screen printing and the substrate during the printing process.

The ink layer is thick and strong, and the texture is rich. The thickness of the ink layer of the offset and embossing is generally 5 micrometers, the gravure is about 12 micrometers, and the thickness of the ink layer printed by the flexographic (aniline) is 10 micrometers. The layer thickness far exceeds the thickness of the above ink layer, generally up to about 30 microns. Thick screen printing for printed circuit boards with an ink layer thickness of up to 1000 microns. The Braille dots are printed with a foaming ink, and the thickness of the ink layer after foaming can reach 1300 μm. The screen printing ink layer is thick, the printing quality is rich, and the three-dimensional feeling is strong, which is incomparable with other printing methods.

Screen printing meshs can be said to be very magical. It is possible to print anything. It can also be printed in color. Easy to use.
