Only after you ‘burn’ the image onto the screen. Emulsion scooper to even spread and lay the emulsion liquid onto the screen. You only want a thin layer. Emulsion is very light sensitive. Do not expose to bright light! Strong light will cure/dry the emulsion. You do not want it to dry until you are ready to imprint the image.

After emulsion is laid. Let is sit and dry in a very dark setting, preferably a dark room

Step Three: Cleaning the Screen (Exposing the Image/mesh) • Pressure wash or hand wash the uncured emulsion until you can see through the screen. The exposed areas should be the shape of the image. • As you can see the black areas on the transparency print are now expose in the screen after washing.
