Difference between screen printing and other printing methods
Different differences from screen printing and other printing methods:
1 Printing is widely adapted. Screen printing can not only print on a plane, but also print on the surface of the surface, spherical and concave surface. On the other hand, the screen printing can not only print on the hard object, but also printed on a soft object, and is not subject to the texture of the body. In addition, in addition to direct printing, screen printing can also be printed in accordance with the needs of the indirect printing method, i.e., first printing on gelatin or silica gel, and then transferred to the substrate. Pingprint, convex, gravure, three major printing methods, generally printed on the plane of the plane. Therefore, it is a wide range of screen printing applications.
2 The ink layer is thick, strong, and rich in texture. The thickness of the cladding and convex ink layer is generally 5 microns, the grade is about 12 microns, and the thickness of the ink layer of flexographic (aniline) is 10 microns, while the ink layer of the screen printing is far more than the ink layer. The thickness is generally about 30 microns. Thick-screen printing for special printing circuit boards, the ink layer thickness can be 1000 microns. Printing a blind word ink printed with foam ink, the foaming rear ink layer has a thickness of 300 microns. The screen printing ink layer is thick, the print quality is rich, strong, which is the other printing method. Screen printing not only can be printed in monochrome, but also a colored and mesh color printing.
3 strong light resistance. The color is bright, because the screen printing is characterized, it can use various inks and coatings, not only the slurry, adhesives and various pigments can also be used, but also coarse pigments. In addition, the screen printing ink provides easy, for example, the light-resistant pigment can be placed directly into the ink, which is another major feature of screen printing. The screen printing products have great advantages with a strong light resistance. According to practice, it is 1.4, which is 1.4, convex is 1.8, and the maximum density value of 1.8, and the maximum density value of the screen printing is 1.8, the maximum density value of the screen printing is 1.8. To 2.0, the light-resistant light resistance of screen printing products is better than that of other types of printing products, and is more suitable for use in outdoor advertising and signs.
4 The print area is large. At present, the area size printed by the printing method of convex printing and controlled printing method is a total size, exceeding the full size, which is limited by mechanical equipment. The screen printing can be printed in large area, and today's screen printing products can reach 3 meters × 4 meters, or even larger.
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, in selecting the printing method, you can avoid weaknesses, highlight the advantages of screen printing, to achieve more ideal printing effects.
