①Stenter has strong printing adaptability
The three printing methods of flat printing, embossing and gravure printing generally can only be printed on flat substrates. And screen printing can not only print on flat surfaces, but also print on curved, spherical, and concave-convex substrates. On the other hand, screen printing can not only print on hard objects, but also on soft objects, without being limited by the texture of the substrate. In addition, in addition to direct printing, screen printing can also be printed by indirect printing according to needs, that is, screen printing on gelatin or silicone plate first, and then transfer to the substrate. Therefore, it can be said that screen printing is highly adaptable and has a wide range of applications.
② Thick ink layer, strong three-dimensional effect, rich texture
The thickness of the ink layer of offset printing and embossing is generally 5 microns, the thickness of gravure printing is about 12 microns, the thickness of the ink layer of flexographic (flexographic) printing is 10 microns, and the thickness of the ink layer of screen printing far exceeds that of the above-mentioned ink layer. The thickness is generally about 30 microns. Thick screen printing for special printed circuit boards, the thickness of the ink layer can be up to 1000 microns. The braille dots are printed with foaming ink, and the thickness of the ink layer can reach 300 microns after foaming. The screen printing ink layer is thick, the printing quality is rich, and the three-dimensional effect is strong, which is incomparable with other printing methods. Screen printing can not only print in monochrome, but also can print in color and screen printing.
③Strong light resistance, bright color
Because screen printing has the characteristics of missing printing, it can use various inks and coatings, not only can use pastes, adhesives and various pigments, but also coarser particles. In addition, the screen printing ink formulation method is simple, for example, the light-resistant pigment can be directly put into the ink for formulation, which is another major feature of screen printing. Screen printing products have a great advantage of strong light resistance. Practice has shown that, according to the maximum density value range measured after using black ink on coated paper for one impression, offset printing is 1.4, embossing is 1.6, gravure printing is 1.8, and the maximum density value range of screen printing can be Up to 2.0, so the light resistance of screen printing products is stronger than that of other types of printing products, and it is more suitable for outdoor advertising and signage.
④Large printing area
At present, the maximum area size printed by general offset printing, embossing and other printing methods is the full-sheet size, and if it exceeds the full-sheet size, it is limited by the Flat Screen Printing Machine. While screen printing can print large areas, today's screen printing products can reach a maximum range of 3 meters × 4 meters, or even larger.
The above four points are the differences between screen printing and other printing, as well as the characteristics and advantages of screen printing. Understand the characteristics of screen printing, in choosing printing methods, you can maximize the strengths and avoid weaknesses, highlight the advantages of screen printing, in order to achieve a more ideal printing effect.
