What is Photo Emulsion?
Photo Emulsion is a light-sensitive substance used in Screen Printing. It forms a stencil on the screen by hardening when exposed to light. Coating the screen with emulsion and exposing it creates a barrier that allows ink to pass through only in desired areas, enabling the transfer of designs onto surfaces.

Instructions for mixing 🎨
Before you start creating Custom Exposed Screens, you'll need to mix the Diazo Sensitiser and Photo Emulsion together, making it scoop coater ready for Coating a Screen with Photo Emulsion.
250ml Photo Emulsion Set: Fill the Diazo Sensitiser bottle to 25% with water (luke warm is good), replace the lid and shake until dissolved, then add to the Photo Emulsion. Then rinse the Diazo Sensitiser bottle out a second time, filling to approximately 25%, shaking and adding to the Photo Emulsion.
Stir the Photo Emulsion well until the contents are fully mixed. Make sure to mix right down to the bottom of the Photo Emulsion, into the corners of the tub. It should be an even colour through-out. After mixing the Photo Emulsion, leave for at least two hours to allow bubbles to disperse before pouring into your Scoop Coater. This is called de-gassing.
1ltr Photo Emulsion Set: Fill the Diazo Sensitiser bottle to 50% with water (lukewarm is good, definitely not hot), replace the lid and shake until dissolved, then add this to the Photo Emulsion. Rinse the Diazo Sensitiser bottle out a second time, filling to approximately 25% full, shaking and adding to the Photo Emulsion.

Want thicker Photo Emulsion?
For coarse fabric, lower mesh counts or a thicker, more viscous emulsion; mix the Diazo Sensitiser with a little less water. You still need to ensure all Diazo Sensitiser has been dissolved though. This will create a thicker emulsion coat and will result in a longer drying time and a longer exposure time. Alternatively, for a thicker stencil, you can do more coats on your screen.
Shelf Life & Storage
Once mixed Hunt the Moon emulsion has a shelf life of about 3-12 weeks. This will depend on how well it is stored. If kept in the fridge it can keep for up to 12 weeks. If you do store it in the fridge, allow it to come back to room temperature before using.
Extreme variations in temperature can have adverse effects. Do not allow it to freeze and we recommend not allowing it to reach temperatures lower than 4°C or in excess of 35°C.
