What are the main differences between screen printing and other printing methods?
① Strong printing adaptability. The three major printing methods of flat printing, embossing printing and gravure printing can generally only print on flat substrates.Screen printing can not only print on flat surfaces, but also on curved, spherical and concave-convex 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, in addition to direct printing, screen printing can also be printed using indirect printing methods as needed, that is, screen printing is first printed on a 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.
②The ink layer is thick, three-dimensional and rich in texture. The thickness of the ink layer for offset printing and embossed printing is generally 5 microns. The thickness of the ink layer for gravure printing is about 12 microns. The thickness of the ink layer for flexographic printing (aniline) is 10 microns, while the thickness of the ink layer for screen printing is much higher. The thickness of the ink layer exceeding the above can generally reach about 30 microns.The thickness of the thick screen printing ink layer specially used for printed circuit boards can be up to 1000 microns.Use foaming ink to print Braille dots and the thickness of the ink layer after foaming can reach 300 microns.The screen printing ink layer is thick and the printing quality is rich and three-dimensional?
This is incomparable to other printing methods.Silk screen printing can not only perform monochrome printing but also process and screen color printing.
③ Strong light resistance and bright colors. Since screen printing has the characteristics of leakage, it can use various inks and coatings. Not only slurries, adhesives and various pigments can be used, but also pigments with coarser particles can be used.In addition, the preparation method of screen printing ink is simple, for example, the lightfast pigment can be directly
It is directly put into the ink and mixed, which is another major feature of screen printing.Screen printing products have the great advantage of strong light resistance.Practice has shown that comparing the maximum density value range measured after one imprint on coated paper using black ink, offset printing is 1.4, embossed printing is 1.6, gravure printing is 1.8, and the maximum density value range of screen printing can reach 2.0 How to start the market positioning of packaging design? Therefore, the light fastness of screen printing products is stronger than that of other types of printing products, which is more suitable for outdoor advertising and signage.
④The printing area is large. Currently, the maximum area printed by offset printing, embossed printing and other printing methods is the full sheet size. If the size exceeds the full sheet size, it is limited by mechanical equipment.Screen printing can print large areas. Today's screen printing products can reach a maximum size of 3 meters × 4 meters or even larger.
The above four points are the differences between screen printing and other printing, and they are also the characteristics and advantages of screen printing.After understanding the characteristics of screen printing, you can maximize your strengths and avoid weaknesses when choosing a printing method, highlighting the advantages of screen printing to achieve a more ideal printing effect.
