The main differences between silk printing and other printing methods

What are the main differences between silk printing and other printing methods

① strong printing adaptability. Generally, the three printing methods of lithography, embossment and gravure can only be printed on flat substrates. Silk printing can be printed not only on the plane, but also on the substrate of curved surface, spherical surface and concave convex surface. On the other hand, silk printing can be printed not only on hard objects, but also on soft objects, which is not limited by the texture of the substrate. In addition, in addition to direct printing, silk printing can also be printed by indirect printing as needed, that is, silk is first printed on gelatin or silica gel plate, and then transferred to the substrate. Therefore, it can be said that silk printing has strong adaptability and a wide range of applications

② the ink layer is thick, three-dimensional, and rich in texture. The ink layer thickness of offset printing and embossing is generally 5 microns, gravure printing is about 12 microns, the ink layer thickness of flexographic printing (aniline) is 10 microns, and the ink layer thickness of silk printing is far more than the above ink layer thickness, which can generally reach about 30 microns. Thick wire printing for special printed circuit boards, with ink layer thickness up to 1000 microns. Braille dots are printed with foaming ink, and the thickness of the foaming ink layer can reach 300 microns. Silk printing has a thick ink layer, rich printing quality and strong three-dimensional sense, which cannot be compared with other printing methods. Silk printing can be used not only for monochrome printing, but also for chromatic printing and color printing

③ it has strong light resistance and bright color. Because silk printing has the characteristics of missing printing, it can use all kinds of inks and coatings, not only slurry, adhesives and various pigments, but also pigments with coarse particles. In addition, the ink allocation method of silk printing is simple. For example, the light resistant pigment can be directly put into the ink for allocation, which is another major feature of silk printing. Silk printing products have great advantages of strong light resistance. The practice shows that according to the range of the maximum density value measured after using black ink to imprint on coated paper, the offset printing is 1.4, the convex printing in the impact position conditioning mechanism, hammer tube size and other aspects is 1.6, and the gravure printing is 1.8, while the maximum density value of silk printing can reach 2.0. Therefore, the Lightfastness of silk printing products is stronger than that of other kinds of printing products, which is more suitable for outdoor advertising For signs

④ large printing area. At present, the maximum area size printed by general offset printing, embossing and other printing methods is the full sheet size. If it exceeds the full sheet size, it is limited by mechanical equipment. Silk printing can be used for large-area printing. Nowadays, the maximum range of silk printing products can reach 3 meters and 4 meters to avoid the impact on the experiment, or even greater

the above four points are the differences between silk printing and other printing, and also the characteristics and advantages of silk printing. Knowing the characteristics of silk printing, we can develop our strengths and circumvent our weaknesses in the selection of printing methods, and highlight the advantages of silk printing, so as to achieve a more ideal printing effect, such as the addition of O-ring fixtures and fixtures for tire industry
