- Tip the scoop up and wait until all of the emulsion has slid down to touch the surface of the screen.
- As soon as the emulsion has made contact with the screen down the whole length of the scoop, start to gently but firmly pull the scoop up along the surface of the screen.
- As the scoop approaches the top of the screen, start to tilt it back such that the emulsion will slide back away from the surface of the screen.
