Screen Printing Exposure Unit 25" x 28" Screen Plate Burning Making Machine

25" x 28" Screen Printing UV Exposure Unit
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. Note: The maximum outer sizes of your screen frame must be within 28" x 25" (71x64 cm). If exceeded these sizes, our exposure unit cannot be covered well, which will affect your exposing effect.
