How to solve the problem of netting that occurs when the screen printing machine is in use?

The situation of sealing the net is largely due to the ink used. To solve the problem of sealing the net better, the method of sealing the net should be discussed from the ink manufacturing and using methods. The sealing of the net due to the large particles of the ink can be solved from the time of manufacturing the ink. The main method is to strictly control the ink particle size should not be too large.

In the printing process, the viscosity of the ink is increased due to the evaporation of the solvent, and an instant drying is formed at the mesh to block the mesh (the conjunctiva after drying) to cause the net sealing phenomenon. This is especially true when using evaporative drying inks. The evaporative drying ink is dried by using a solvent, so it is necessary to select an appropriate solvent to control the drying speed during printing, and also pay attention to the ventilation of the production workshop, temperature and humidity conditions. When choosing inks, consider the influence of climate. Generally, quick-drying inks are used in winter, and late-drying inks are used in summer. In the spring and autumn, inks with dryness between the above two are used.
