The difference between screen printing with silicone ink and other printing

Aug 21, 2021

Strong printing adaptability

The three printing methods of lithography, embossing and gravure can only be printed on flat substrates. Screen printing can be printed not only on the plane, but also on the substrate with curved surface, spherical surface and concave convex surface. On the other hand, screen 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, screen printing can also be printed by indirect printing as needed, that is, screen printing on gelatin or silica gel plate first, and then transfer to the substrate. Therefore, it can be said that screen printing has strong adaptability and a wide range of applications.


Strong three-dimensional sense

With rich 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 (aniline) printing is 10 microns, and the ink layer thickness of screen printing far exceeds the above ink layer thickness, generally up to about 30 microns. Thick screen printing for special printed circuit boards, with ink layer thickness up to 1000 microns. Braille braille is printed with foamed ink, and the thickness of foamed ink layer can reach 1300 microns. Screen printing has thick ink layer, rich printing quality and strong three-dimensional sense, which can not be compared with other printing methods. Screen printing can not only monochrome printing, but also chromatic printing and screen color printing.


Strong light resistance

Because screen printing has the characteristics of missing printing, it can use various inks and coatings, not only slurry, adhesive and various pigments, but also pigments with coarse particles. In addition, screen printing ink is easy to deploy, for example, the light resistant pigment can be directly placed in the ink, which is another feature of screen printing. Screen printing products have great advantages of strong light resistance. The practice shows that according to the maximum density range measured after one embossing on coated paper with black ink, the offset printing is 1.4, the embossing printing is 1.6, and the gravure printing is 1.8, while the maximum density range of screen printing can reach 2.0. Therefore, the light resistance of screen printing products is stronger than that of other kinds of printing products, which is more suitable for outdoor advertising and signs.


Large printing area

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. Screen printing can be used for large-area printing. Today, the maximum range of screen printing products can reach 3 meters × 4 meters or more.


The above four points are not only the difference between screen printing and other printing, but also the characteristics and advantages of screen printing. Understand the characteristics of screen printing, in the selection of printing methods, we can develop strengths and avoid weaknesses, highlight the advantages of screen printing, so as to achieve a more ideal printing effect.
