Expose screen to UV light
- Place your transparent face up on the glass plate at the exposure unit.
- Place the screen over the transparent on the glass plate.
- Close the cover of the exposure unit and close the locks.

Wash out the non-exposed parts
Make both sites of the screen wet with the hose, wash the non-exposed parts.

In the drying drawers, don't place it in a drawer above a non exposed screen to avoid dripping water on a non exposed screen.
