Printing adaptability of screen printing mesh
The three printing methods of lithography, embossing and gravure generally only print on flat substrates. 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, besides direct printing, screen printing can also be printed by indirect printing method as needed. That is, first screen printing on gelatin or silicone plate, and then transferred to the substrate. Therefore, it can be said that screen printing is highly adaptable and has a wide range of applications.
Thick ink layer, strong 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. 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 can be performed not only in monochrome, but also in color registration.
Light resistance is strong
Because screen printing mesh has the characteristics of missing printing, it can use various inks and coatings, not only using pastes, adhesives, various pigments, but also coarser pigments. In addition, the screen printing ink preparation method is simple. For example, lightfast pigments can be directly placed in the ink, which is another major feature of screen printing. Screen printing products have great advantages in light resistance. It has been shown through practice that the maximum density value range measured after a single imprint of black ink on a coated paper is compared. The offset printing is 1.4, the embossing printing is 1.6, and the gravure printing is 1.8. The screen printing maximum density value range can be Up to 2.0, so the light resistance of screen printing products is stronger than other kinds of printing products, and is more suitable for outdoor advertising and signage.
Large print area of screen printing mesh
At present, the size of the area printed by offset printing, embossing and other printing methods is at most the full-sheet size, which exceeds the full-sheet size and is limited by mechanical equipment. Screen printing can be used for large-area printing. Today's screen printing products can reach a maximum of 3 meters by 4 meters or even larger.
The above four points are the difference between screen printing and other printing, but also the characteristics and advantages of screen printing mesh. Hope that article can help you choose suitable printing.
