I believe that our friends who often love to watch movies may have seen printing money or the renminbi. A while ago, the relatively hot movie in China was called "The Warriors", and Aaron Kwok and his wife made a fake US dollar. Whether you are making real money or a ghost ticket. All we should know is that they are printed on screen printing meshs. So why not use a screen printing mesh?
But do you know how the renminbi is done?
It took a month for a white paper to become a pink "Mao Grandpa" in the printing factory workers. They are no longer money
Just a product, how is this money made?
First of all, don't underestimate the original white paper. It is a special paper made of cotton linters. A screen printing mesh is used for intermediate printing. Why use screen printing meshs?
Print adaptability
The three printing methods of lithography, embossing and gravure printing can generally only be carried out 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. On the other hand, screen printing can be printed not only on hard objects, but also on soft objects, without being limited by the texture of the substrate. In addition to this, in addition to direct printing, screen printing can also be printed by indirect printing method as needed, that is, screen printing on gelatin or silicone plate, and then transferred onto the substrate. Therefore, it can be said that screen printing is highly adaptable and has a wide range of applications.
Strong sense of three-dimensional
The texture of the rich offset and embossed ink layer is generally 5 microns, the gravure is about 12 microns, the flexographic (aniline) printed ink layer is 10 microns thick, and the screen printed ink layer thickness far exceeds the above ink. The thickness of the layer is generally up to about 30 microns. Thick screen printing for printed circuit boards with an ink layer thickness of up to 1000 microns. Braille is printed with foaming ink, and the thickness of the ink layer after foaming can reach 1300 microns. 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 can be done not only in monochrome, but also in color and screen color printing.
Why do we usually use Mao’s grandfather to look so fascinating? It’s because the screen printing meshis printed with a three-dimensional look. And compared to other printing methods. The printing accuracy effect is also more careful.
