3.The barrier layer is thick, the three-dimensional effect is strong, the coverage is strong, and the texture is rich
Screen printing is different from other printing methods and plate making methods. When making plates, the more times the photosensitive adhesive is applied, the higher the thickness of the ink coverage during printing, and the required printing thickness can be achieved by multiple printing on the substrate. Therefore, the thickness of ink coverage of screen printing can be from 6 microns to 300 microns, and the thickness of letterpress printing and lithographic printing is only a few microns. There is no comparison at all, even if the gravure printing is known for its printing layer feel, it can only reach 15 microns. , it can be seen from the comparison that the ink coverage of screen printing is much stronger than that of other printing methods. The brightly colored ink layer of the finished product printed by screen printing is thick, because chemical components that can keep the color vivid for a long time can be added, so the color preservation period is longer. These advantages are compared with offset printing and gravure printing. they are incomparable. When screen printing, the ink layer is thick and the three-dimensional effect is strong. For oil painting reproduction that requires high texture, screen printing
It can be said to be the best choice. In the electronic industry printing, screen printing also undertakes the printing of circuit boards. Screen printing can be printed with various printing coatings to achieve a special touch. Foaming ink is one of them. After printing, the bulge and surface texture are obvious. It is widely used in Braille books and is convenient for blind people to touch. With the continuous innovation and development of screen printing technology, we can now see many oil paintings, traditional Chinese paintings, advertising paintings, etc. reproduced by screen printing on the market. The reproduction of these high-level handicrafts is the use of screen printing. Layered printing method, repeated printing for many times to complete the reproduction of artwork layer by layer, and finally achieve the effect that the screen has no dots and is fake. This kind of high-level reproduction of works of art cannot be achieved by other printing methods.
The ink layer of screen printing is thick, and the printed color has a dual feeling of touch and vision, which is very different from the other three printing methods. Other printing methods can only achieve flat printing, or more subtle printing. tactile sensation. If the general printing method is to do pure white printing on all black paper, it must be printed 3 to 4 times on the same part, while screen printing only needs to be printed once because of its strong printing coverage. Carefully observe the screen printed products, not only the ink layer has a strong sense of layering, but also has a good tactile feel with a certain three-dimensional sense, and the thickness of the ink layer printed by screen printing can be determined according to the number of printings, or the application of photosensitive glue during plate making. It is determined by the thickness. The thickness of screen printing can vary from 6 microns to 1000 microns. It can be seen that the ink layer of screen printing can be adjusted. Different thicknesses can be applied for different designs to achieve different printing effects. 

4.Suitable for use with various types of inks or coatings

Screen printing inks are actually various types of coatings. The wide range of inks used has exceeded the definition of ordinary inks. The types of coatings that can be used in screen printing include oil-based, water-based, solid powder, paste, paste, adhesive, synthetic resin type, etc. Therefore, screen printing inks are sometimes collectively referred to as “printing materials”. In general, it has the characteristics that any kind of paint can be used for printing, and there is almost no requirement for the fineness of the printing paint. As long as the ink and paint that can pass through the fineness of the screen mesh can be used, whether it is a letterpress gravure Or flat offset printing is limited by the printing plate and the machine, and the ink used is relatively high, and the particles are required to be fine and smooth. Screen printing can print monochrome, multi-color overprinting, multi-color block overlay printing, and hanging screen overprinting.
5.Strong light resistance

Since screen printing is suitable for all kinds of paints and is not affected by the thickness of the paint particles, even paints with relatively coarse particles can be used. Because of this remarkable feature of screen printing, in order to achieve the printing effect of light fastness or fluorescent effect , you can directly add the lightfastness or fluorescent paint with coarser particles into the printing paint, and directly mix and print without going through complicated steps, so that the printed product can permanently keep the gloss free from changes in light and temperature.
effects, and even reflective materials can be added to make the print glow at night. The ink used for screen printing is also very convenient to deploy, and the paint of the ingredients to be added can be directly added. Because the silk-screen printing process can simply add light-resistant coatings, the printed products have strong light-fastness and can be widely used in some advertisements that are exposed for a long time, such as large-scale outdoor advertisements and trademarks, so that they can not fade for a long time.
6. Flexible and diverse printing methods

Screen printing, like offset printing, gravure printing, and letterpress printing, is a printing method that can be industrialized and mass-produced, in order to produce printed products in large quantities. At the same time, it has the advantages of easy learning, convenience, cheap materials, flexible and diverse printing methods, fast and labor-saving printing process, simple and easy to master technology, etc., which are incomparable with the other three printing methods, so it has developed in recent years. quick. It is not limited by the size of the enterprise.
Mechanization can be used for printing production, and manual printing can also be mass-produced. Of course, quite a lot of screen printing products are realized by hand printing, which is also the development of screen printing.
The main reason for the faster development is that the investment is much smaller than other printing methods. Screen printing provides a variety of realization means for designers’ design creativity. Because it has a wide range of applications, it is compatible with almost all inks and substrates. 

Screen printing provides a variety of realization means for designers’ design creativity. Because it has a wide range of applications, it is compatible with almost all-cut inks and substrates. Moreover, it has great design potential, and experimental results of innovative design applications emerge in an endless stream. If a newly discovered or newly discovered material is introduced into the field of graphic design, the first experimental process worth trying is screen printing, which can bring designers fresh results beyond imagination. Screen printing can be done byIt is carried out by automated machinery and can also be carried out on a traditional manual printing table. It can be mass-produced or hand-printed to produce different effects.
