Advantages of screen printing

Around us, screen-printed products are used in almost every aspect, and screen-printing is widely favored by the market for its many advantages. Screen printing is an all-purpose printing technology. Except for water and air, you can't think of it, and you can't print without it. Biyin Bazaar will talk about the advantages of screen printing today, and analyze the all-purpose screen printing technology.

1. Low cost and quick effect. Screen printing can be produced by mechanization or manual operation. Its investment can be large or small. It can be engaged in individual manual production from thousands of yuan to tens of millions of yuan to build a modern screen printing factory. Those simple printing that cannot be done by lithography, embossing and gravure printing can be done with silk screen printing. Screen printing can be divided into industrial screen printing and fine art screen printing. Fine art screen printing can be used to print exquisite prints and copy precious oil paintings. Its products have bright colors and thick ink layers. The main body of the picture is strong, which is beyond the reach of other printing methods. 2. It is suitable for printing on the surface of irregular substrates. Screen printing is very flexible. In addition to printing on flat objects, it can also be printed on curved, spherical or uneven surfaces, such as various glassware, plastics, bottles, lacquerware, woodware, etc., It can print what cannot be printed by lithography, letterpress, and gravure methods.

3. Strong adhesion and good ink adhesion. Due to the characteristics of the screen plate, the ink is directly attached to the surface of the substrate through the screen holes. According to the requirements of the substrate material, it can be printed with ink, or with various coatings or color pastes, glues, etc. Other printing methods are limited by the finer requirements on the particle size of the pigment in the ink.

4. The ink layer is thick and the three-dimensional effect is strong. Among the four printing methods, the ink layer of screen printing is thicker, the texture of pictures and texts is rich, and the three-dimensional effect is strong. The ink layer of offset printing is 1.6 microns, the embossing ink layer is about 5 microns, the ink layer of gravure printing is about 12.8 microns, the thickness of the ink layer of flexographic printing is 10 microns, and the thickness of the ink layer of screen printing can reach 60 microns. Thick film screen printing ink layer thickness can reach about 1 mm. Screen printing is used to print Braille, and the thickness of the ink layer can reach 300 microns. The method is to directly make a positive image on the screen plate according to the original through a Braille machine, and immediately heat and dry after the screen printing foaming ink printing, which can form Braille.

5. Strong light resistance and good color formation. If compared according to the maximum density range measured after using black ink on coated paper, the offset printing is 1.4, the embossing is 1.6, the gravure printing is 1.8, and the maximum density range of the screen printing can reach 2.0, so the silk screen Screen printing is extremely lightfast, and its color formation is much better than offset printing. In offset printing, if you want to use the proofing mechanism to take the opaque printing surface covered by white, you need to reverse the same part 3-4 times, and screen printing only needs to print once. In terms of the color quality of the printed product, even if it is the same color printed product with a very light color, the texture and color of screen printing far exceed offset printing. The thickness of the ink layer for screen printing can be thicker or thinner. For example, in four-color screen printing, it is required that the ink layer of each color is not thick, but a thin ink layer. The method of thinning the ink layer is to make the ink layer of screen printing thinner or even thinner by changing the variable factors such as printing speed, ink viscosity, screen thickness, squeegee shape, printing pressure and inking angle.

6, a wide range of substrates. It can be paper, cardboard, wood, metal, textiles, plastic, cork, leather, fur, ceramics, glass, decals, transfer paper, and a combination of various materials, so screen printing is not only in the printing industry Benzhi Week In addition to the application of everything, it is also widely distributed in the printing and dyeing, clothing, signage, radio, electronics, ceramics and packaging and decoration industries.

7. The printing format is large. Now litho' letterpress, gravure and flexographic printing are limited by the size of the printing format, while screen printing can be printed in large format. Especially at present, with the rapid development of the advertising market, the proportion of large-scale outdoor advertising prints in the advertising market is increasing day by day. Now the largest screen printing outdoor advertising can reach 2.2x3.8 meters and 2.2x4 meters.
