   The key link of open type rotary screen printing machine printing quality are that the open type rotary screen printing machine printing speed and printing work pressure is controlled.

  1. How to manipulate the working pressure of the open type rotary screen printing machine

  The effect of the open type rotary screen printing machine printing work pressure is to ensure that the screen and the printing process surface have sufficient line contact, and under this prerequisite, the lower the printing work pressure of the open type rotary screen printing machine, the better. Because the greater the working pressure, the scraper The contact with the screen is good, but the deformation level of the screen and the level of the squeegee placed in the hole ring are high, so the amount of ink transfer is small, and the deformation of the squeegee of the open type rotary screen printing machine is larger, which will affect the oil filling situation. It will cause great harm and will expand the deformation of the screen, and the sliding friction between the open type rotary screen printing machine scraper and the screen will also increase, which will not only increase the friction on the screen but also endanger the open type rotary screen. printing machine printing speed.

  2. How to control the printing speed of open type rotary screen printing machine

  The printing speed of the open type rotary screen printing machine refers to the speed at which the squeegee advances during the printing of the open type rotary screen printing machine. The one-knife assist is very slow, although the ink filling is good, there will be printing ink penetration at the edge of the pattern, causing the pattern to expand; open The printing speed of the type rotary screen printing machine is too fast, which will result in insufficient ink filling and insufficient printing speed, and will also cause the ink release speed to fail the printing speed, causing the adhesion section to be too long and harm the printing quality. Printing ink viscosity, large flowability, The printing speed of the open type rotary screen printing machine is moderately slow, and the opposite is also true; the screen mesh is high, the total area of ​​the ring is small, and the speed of the squeegee during the wire brushing can be slow. Not only must be grasped during the whole printing process The speed of the squeegee speed should pay attention to the uniformity of the scraping speed. If it is fast and slow, vertical marks will appear in the printing process, which will harm the printing quality.
