1: How to manipulate the working pressure of screen printing ink
The effect of screen printing press working pressure is to ensure that the screen and the printing process are in sufficient line contact. Under this prerequisite, the lower the screen printing press working pressure, the better. Due to the greater working pressure, the scraper blades are in good contact with the screen. However, the level of deformation of the screen and the level of the blade inserted into the hole ring are high, so the amount of ink transmission is small, and the deformation of the screen printing machine blade is also greater, which will cause great damage to the oil filling situation and will also make the screen The deformation is enlarged, and the sliding friction between the screen printing machine blade and the screen will also increase, which not only increases the friction on the screen, but also harms the printing speed of the screen printing machine.
2: How to control the printing speed of screen printing machine
The printing speed of the screen printing machine refers to the speed at which the scraper advances during the printing of the screen printing machine. One-knife assistance is very slow. Although the ink filling is good, the infiltration of the printing ink will occur at the edge of the pattern, causing the pattern to expand. Insufficient ink filling, imprints are not detailed, and the speed of ink release cannot be printed, resulting in too long adhesion sections and jeopardizing printing quality. Printing ink viscosity, large flowability, screen printing machine printing speed is moderately slow, the opposite is also true; silk The screen mesh has a high mesh count and a small total area of the perforated ring. The speed of the scraper can be slower during the wire brushing. During the entire printing process, not only the speed of the scraper must be grasped, but the speed of the scraper must be balanced. Slow time, vertical traces will appear on the printing process, which endangers printing quality
