Working Principle

Screen printing screens are coated with a light sensitive emulsion using a scoop coater. When the emulsion is dry, place a positive print of your image 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.

 

This Precise LED Vacuum UV Exposure Unit is equipped with special LED 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 expsoure time, then it will make the screens and transparency film close on the glass tightly by evacuating the air of the vacuum chamer emerging from the rubber blanket. When the set time is up, it will deflate automatically, then the exposure is finished. Please cut off the power supply.

 

It has the same exposure effect with the exposure unit exposed of iodine gallium light. Even if its exposing time is a little longer, but because of its small volume, light weight, low cost and easy transporation, which is much fit for small business and family workshop for making screens with high precision.
