The key link of the quality of the printing quality of the open rotary screen printer machine is that the printing speed and the working pressure of the open rotary screen printing machine are controlled by the quality. The effect of the working pressure of the open rotary screen printing machine is to ensure that the screen and the printing process surface have sufficient line contact. Under this prerequisite, the lower the working pressure of the open rotary screen printing machine, the better. Because the greater the working pressure, the better the contact between the scraper and the screen, but the degree of deformation of the screen and the degree of the scraper placed in the orifice ring are high, so the amount of ink transfer is small.
The greater the deformation of the blade of the open rotary screen printing machine, this will cause a great harm to the condition of oil filling, and will also expand the deformation of the screen, and the gap between the blade of the open rotary screen printing machine and the screen The sliding friction will also increase, which not only increases the friction on the screen, but also jeopardizes the printing speed of the open rotary screen printing machine. The printing speed of the open rotary screen printing machine refers to the speed at which the scraper travels when printing on the open rotary screen printing machine.
The knife assist is very slow. Although the ink filling is good, the printing ink will infiltrate on the edge of the pattern, causing the pattern to expand; the printing speed of the open rotary screen printing machine is too fast, it will cause insufficient ink filling, the imprint is not detailed, and Will lead to ink release speed not printing speed, the formation of adhesion section is too long and endanger the printing quality. Printing ink viscosity, poor circulation.
The printing speed of the Hot Air Stenter is moderately slow, and vice versa; the screen mesh with a high mesh screen and a small total area of the hole ring can slow down the speed of the scraper when brushing. In the whole printing process, not only should we grasp the speed of the scraper speed, but also need to pay attention to the symmetry of the scraping speed. Assuming that it is fast and slow, vertical marks will appear on the printing process, which will harm the printing quality.
