Vacuum Exposure Unit 110V
ASC6050ZK Precise Vacuum UV Exposure Unit is equipped  with special UV lamps and auxiliary vacuum suction device. After putting  the screens and well printed transparency film on the glass, close its  cover and let it work after set the needed vacuum and exposure time,  then it will make the screens and transparency film close on the glass  tightly by evacuating the air of the vacuum charmer emerging from the  rubber blanket. When the set time is up, it will deflate automatically,  and then the exposure is finished. Please cut off the power supply.

Working principle
Screen printing screens are coated with a light sensitive emulsion using  a scoop coater. When the emulsion is dry, place your image with a  positive print on the screen. Once you burn the screen, the emulsion  that did not get any UV will wash out of the screen exposing the tiny  pin holes. The surrounding areas that were exposed to UV will be cured.  Hence the ink will pass through screen onto your substrate.
Special Tips
The vacuum pumping area (sizes of the rubber blanket) is 19.6”*23.6”  (50*60cm), (If your screen is oversized, please buy cautiously!)
