At 6-7 using white 4x20w white UV fluorescent bulbs exposure is around 2 minutes At 3 exposure it takes just about 1 minute to expose. Using a photopolymer emulsion (compared to a diazo-based emulsion) when you have a low UV light source will make a huge difference toward success or failure when making a stencil. I have recently moved and am not sure if the climate is the problem, but the Emulsion is drying to fast and hard before I burn the screen. First, you will make a transparency, expose it to burn the screen, and then print. Photopolymer liquid emulsions (and photopolymer capillary film) work well even with poor light sources. ![]() Manufacturers developed photopolymer emulsion products because they know that many screen printers use an exposure light source that is less than ideal. It exposes very quickly and has a wide exposure time range. Photopolymer emulsion is very sensitive to light.

If you think of emulsion (or capillary film) as the “photographic film” used to make your stencil, think in terms of speed and light sensitivity. Communicate recommendation to dry a minimum of four hours, with overnight dry- time being ideal. Stronger lights will require less time to develop, perhaps as little as 15 minutes depending on conditions. While the light source will determine what kind of art you can use to make a stencil, the type of emulsion or capillary film that you use is actually more important. ![]() Most people who want to build their own exposure unit mistakenly think that the light source is the most important consideration. ![]()
