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.
Strong light resistance
Bright color Because screen printing has the characteristics of missing printing, it can use various inks and coatings, not only pastes, adhesives and various pigments, but also coarse particles. In addition, the screen printing ink is simple to prepare, for example, the light-resistant pigment 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 by practice that the range of maximum density values measured after one embossing on the coated paper using black ink is 1.4, offset printing is 1.6, gravure is 1.8, and screen printing has a maximum density value range. Up to 2.0, the lightfastness of screen printing products is stronger than that of other types of printed products, and it is more suitable for advertising and signage outdoors.
Large printing area
Generally, the printing area such as offset printing and embossing prints a maximum size of a 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 x 4 meters or even larger.
