Several ways to select screen printing mesh have been introduced before. However, the choice of screen printing mesh is not a simple thing. In addition to considering the screen, various constraints related to the cost of the ink, the substrate, and the like are also considered. Grasp the selected method and pay attention to the relevant issues, select the appropriate screen can be handy. When selecting a screen, you should pay attention to the following aspects.
1. First, consider the difficulty of ink passing through the screen. Generally, consider more aspects in this regard. High-transparency inks for intermediate-tone inks, pigment particles are relatively fine, and the ratio of pigment particles to the pigment carrier is higher, and the ink passing property is better. This ink can also pass well when using a high-mesh screen. Gnerally speaking, plastic ink passability is better. However, special-purpose inks, inks with high pigment concentration, although fine particles, are relatively poor in passability.
2. If the surface of the substrate is rough, a lower mesh screen is generally used.
Such as leather, canvas, foam sheet, wood and other materials printed. Since the surface of the substrate is rough and the ink absorption is strong, a mesh with a lower mesh number is used to ensure that enough ink passes.
3. Select the screen according to the fineness of the original text line. Contrary to the above situation, high-mesh screens are generally selected for fine lines.
4. When selecting the screen, cost will also be taken into consideration. In the premise of meeting the printing requirements, the lower price screen printing mesh is also attractive.
