Stainless steel wire printing mesh printing ink precautions

Stainless steel wire printing mesh has better hot meltability, it is an ink that can be applied to hot melt, and it is a special advantage of stainless steel itself.

Hot melt resistance is good, and the use of ink on Stainless steel wire printing meshs also requires attention to some problems. When the particles of the pigment and other solid materials in the screen printing ink are large, the phenomenon of blocking the mesh is apt to occur. In addition, the mesh size and the through-hole area of the selected mesh are smaller than the particle size of the ink, and it is also one of the reasons why the ink of the coarser particles is not easily passed through the mesh. The paste caused by the large particles of the ink can be solved from the time of manufacturing the ink, and the main method is to strictly control the fineness of the ink.

The ink used in the Stainless steel wire printing mesh is relatively easy to dry and is prone to paste failure. This phenomenon is particularly prominent when using a volatile dry type ink, so it is necessary to select an appropriate solvent to control the drying speed during printing. When selecting inks, the effects of climate should be considered. Generally, fast-drying inks should be used in winter. In summer, dry-drying agents should be added to the inks. If paste-forming is used in the case of late-drying agents, other types of inks must be used.

In addition to the precautions for the use of inks, Stainless steel wire printing meshs have a wide variety of substrates. The geological properties of the substrate are also a cause of the paste-forming phenomenon. For example, the surface smoothness of paper, wood, and other substrates is low, and the surface strength is relatively poor. In the process of printing, there is a phenomenon in which powder is dropped or hair is lost. Therefore, it causes a foul phenomenon.
