- The plates are brought into the spray booth area where the dye gets sprayed on one side only.

- Plates are then moved to the dark room area where black fluorescent lights are used to identify the pin holes or cracks.
- All pin holes and cracks are marked with a black felt permanent marker.
- Dye is washed off.
- Plates are dried.
