Instead, rely on the excess deposits already on the screen to cover the center band. Wipe up any excess emulsion immediately after finishing the coating and place the screen face up in a dark closet or room to dry. This will take about 3 hours under normal conditions, but can be speeded up considerably by using a fan to blow air over the surface of the screen. Use a plastic spatula to push the excess emulsion out of the scoop coater and into a storage container. Have a pre-prepared place set up where the newly coated screen can dry.
Coating takes a little practice.
Once you commit to the coating action, follow through until you reach the top. Don't apply the emulsion thickly and don't re-coat any areas. If you have missed an area, try to use any excess emulsion already on the screen to coat that area. Dry photo emulsion is difficult to remove. Don't let it dry in your scoop coater or it will ruin it.
