Choose the appropriate screen according to the nature of the substrate and the requirements of the printed matter.
As for mesh screen printing has a wide range of substrates, there are many types of substrates, and the characteristics of the substrates are also different. Therefore, when choosing the printing mesh, it is necessary to choose according to the material of the substrate.
When the substrate is a textile, such as cloth, scarves, school bags, etc., nylon mesh can be used; For mesh screen printing, when the printed matter is postcard, wallpaper, calendar, etc., thick nylon mesh can be used; when the substrate is glassware, metal container, For wood, ceramics, plastic products, toys, monofilament nylon mesh, thin polyester mesh, stainless steel wire mesh, can be used; when the substrate is integrated circuit, semiconductor component, insulating cloth, TV component, etc., Could choose polyester mesh, stainless steel wire mesh. This selection can also be said to based on the different properties of the different screens.
According to the surface of the substrate is rough situation the choice of screen is different. When the surface of the substrate is rough, a lower mesh count screen is generally used. For mesh screen printing such as leather, canvas, foam sheets, wood, etc., since the surface of the substrate is rough and the ink absorption is strong, need to choose a lower mesh count is used to ensure a sufficient amount of ink passes. The use of printed materials is different, and the final printing effect is different. The quality requirements of the prints is not very high can be used with lower mesh count. For prints with higher quality requirements, such as high line fineness, it is necessary to select A higher mesh count screens.
