The MEDIUM micro registration with back clamp is designed to improve production speed and print quality on the SMALL series of the WEISS screen print carousels. It is manufactured with three large adjustment knobs with a good grip. These three knobs give you the flexibility of adjusting the screen into position with minimal effort. When the screen is in position the center knob on the micro registration is tightened and the MEDIUM screen print carousel is set and ready to be used.
