There are many printing methods in the printing industry, including screen printing and other printing methods. Many consumers want to know how the difference between screen printing and other printing of screen printing meshs is different. Professionals engaged in the production of wheat stone technology will inform you of the following.
In the screen printing process of screen printing, the difference between screen printing and other printing methods is as follows:
First, the screen printing mesh has strong light resistance, bright color and leakage printing characteristics, so it can use various inks and coatings, not only can use slurry, adhesive and various pigments, but also can use particles. In addition, the screen printing ink is easy to mix, for example, the light-resistant pigment can be directly placed in the ink, which is another major feature of screen printing. The screen printing product has strong light resistance. Great advantage. It has been shown by practice that the range of maximum density values measured after one embossing on the coated paper using black ink is 1.4 for offset printing, 1.6 for embossing, and 1.8 for gravure printing. The maximum density range is up to 2.0, so the lightfastness of screen printing products is stronger than that of other types of printed products, and it is more suitable for outdoor advertising and signage.
Second, the printing adaptability of strong lithography, embossing, gravure three printing methods can only be printed on a flat substrate. Screen printing can not only print on the plane, but also on the surface, spherical and concave Printing on the surface of the substrate. On the other hand, screen printing can be printed not only on hard objects, but also on soft objects, regardless of the texture of the substrate. In addition to screen printing, in addition to direct printing In addition, it can also be printed by indirect printing method according to need, that is, screen printing on gelatin or silicone plate, and then transferred to the substrate. Therefore, it can be said that screen printing has strong adaptability and wide application range.
Third, the ink layer is thick, the three-dimensional effect is strong, the texture is rich in offset and embossed ink layer thickness is generally 5 microns, gravure is about 12 microns, flexographic (aniline) printing ink layer thickness is 10 microns, and the screen The thickness of the printed ink layer far exceeds the thickness of the above ink layer, generally up to about 30 microns. Thick screen printing for special printed circuit boards, the thickness of the ink layer can be up to 1000 microns. Braille dots are printed with foaming ink. Yu, after foaming, the thickness of the ink layer can reach 300 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 not only be monochrome printing, but also can be carried out. Color and screen color printing.
