Ulano Proclaim Screen Print Emulsion, sets the industry standard for screen printing emulsion. Check out our screen printing tutorial (you can skip to Step 3, approx 4min 53 secs) for the section showing how to prepare the emulsion and coat the screen. if you are using Plastisol Inks and looking for a Photo Senstive Emulsion then Ulano Proclaim is a good choice.
When used with exposure units/Light sources other than our 1000watt halogen light or LED lamp, exposure times will vary:
- Pre-Sensitized – up to 12 months
- Sensitized – 4-8 weeks
Emulsion is best stored in a cool dark environment where adverse weather conditions do not occur. If the storage temperature is warm or hot, or below freezing, emulsion has a tendency to react and will pass its expiry date.
The most obvious way of telling whether the emulsion has expired is upon ‘clearing the image’ with water, the sensitizer will not have reacted to the light source and the emulsion will simply wash out completely.
