You may be very confused about something.You may particularly want to know what are the advantages of screen printing? what is the difference between silk screening and other screen printing？With the increasing demand for printed matter, a large number of spot colors and transition colors in printed matter, as well as the high-precision requirements of customers for printed patterns, the traditional screen printing process has been unable to meet the needs of the market. Screen printing Compared with other printing methods, advantages of screen printing has four aspects:
what are the advantages of screen printing
1. screen printing adaptability.Print, letterpress, gravure three printing methods generally can only print on a flat substrate. The screen printing can not only print on the plane, you can also curved, spherical and concave and convex printing on the substrate. On the other hand, screen printing can not only print on hard objects, but also print on soft objects regardless of the texture of the substrate. In addition, screen printing in addition to direct printing, but also can be used according to the need for indirect printing method of printing, that is first screen printing in gelatin or silicone version, and then transferred to the substrate. So we can say that screen printing adaptability, a wide range of applications.
2. thick ink layer, strong sense of three-dimensional texture rich offset and embossing ink layer thickness is generally 5 microns, gravure is about 12 microns, flexographic (aniline) printing ink layer thickness of 10 microns, and screen printing Ink layer thickness far exceeds the thickness of the ink layer, generally up to 30 microns. Printed circuit board with a thick screen printing, ink layer thickness up to 1000 microns. Printed Braille dots with foamed ink, foamed ink layer thickness up to 1300 microns. Screen printing ink thick, rich print quality, strong sense of three-dimensional, which is other printing methods can not be compared. Screen printing can not only monochrome printing, but also for color and screen color printing.
3. light fastness, bright color Screen printing with leakage characteristics, so it can use a variety of inks and coatings, not only can use the slurry, adhesives and various pigments, you can also use the coarse particles of pigment. In addition, the screen printing ink deployment method is simple, for example, can put the light-resistant pigment directly into the deployment of ink, which is another major feature of screen printing. Screen printing products have a great advantage of lightfastness. Practice has shown that by using black ink in a coated paper after a maximum measured density range for comparison, offset 1.4, embossing 1.6, gravure 1.8, and screen printing the maximum density range Up to 2.0, so screen printing products lightfastness than other types of printed products, lightfastness, more suitable for outdoor advertising, signs use.
4. large current printing area General offset printing, letterpress and other printing methods of printing 
the size of the largest area for the whole Zhang size, more than the full size, mechanical and mechanical constraints. The screen printing can be large-area printing, the largest screen printing products today up to 3 m × 4 m, or even larger.
what are the advantages of screen printing?The above four points are the difference between screen printing and other printing, but also the characteristics and advantages of screen printing. Understand the characteristics of screen printing, select the printing method, you can avoid weaknesses, highlighting the advantages of screen printing, in order to achieve a more ideal printing results.
