1. Selection of screen printing screen
Reasonably select the mesh number of the wire mesh. The mesh number of the wire mesh indicates the number of mesh wires in each linear unit length of the wire mesh. The larger the number, the finer the wire mesh. Printing quality is particularly important. The larger the mesh, the finer the mesh, and the higher the number of meshes per centimeter. On the screen printing plate, the lines and small dots are easier to reproduce; if the mesh is smaller That is, thicker silk screen plate making can never print subtle levels. Naturally, the finer the screen is not the better, it depends on the use of the printing job, the original and the type of ink used. Reasonably select the wire diameter and weaving method of the wire mesh and the elongation rate of the wire mesh. It is recommended to use a wire mesh with a low elongation rate here, which has a good guarantee for the printing accuracy of the precision screen.
2. Selection of screen printing aluminum frame
There are also many types of aluminum frame profiles. When selecting aluminum frame profiles, the size of the screen frame can be determined according to the size of the printed graphics, and the corresponding profiles can be selected according to the size of the tension. Under normal circumstances, it is recommended to use high strength. The aluminum frame can not only ensure the accuracy of graphic printing, but also prolong the service life of the aluminum frame.
3. Selection of photosensitive adhesive for screen printing
There are many brands of photosensitive adhesives on the market. In terms of price, the price is dozens of yuan, and the price is hundreds of yuan. The professional manufacturer of capacitive high-precision screen printing and precision screen printing is recommended to use high resolution and exposure. Photosensitive glue with wide time range and superior resolution. This can guarantee the accuracy of graphics, so that the screen version can be realized: fonts, lines and graphics can be clear, sharp, beautiful and durable.
4. Selection of screen glue for screen printing
There are also many kinds of sticky mesh glue on the market. Usually, it is divided into yellow colloid and red colloid. The yellow sticky mesh glue is also called single yellow glue. The maximum temperature is less than 45 degrees, and the performance of solvent resistance, screen printing washing water and ink thinner is relatively poor at the printing site.
