Screen Printing Forum

Hi, i'm yet to try out screen printing ...
but I was just wandering, which stages of the screen printing stages NEED to be under subdued/red lighting? any help would be great! thanks

The emulsion is uv sensitive in the pot, when coating, when drying and during exposure. When it's washed out it may benefit from a bit of post exposure to harden it up.

Coating the screen with emulsion up to washing the screen out after exposure. All this should be done in a dark room or light safe room.
