Speedball Diazo Kit (Photo Emulsion Sensitizer & PE Remover

Here’s how to use it:

1. Mix the photo emulsion and sensitizer to create the resist. This sensitized mixture can be stored for 2 months at room temperature or up to 10 months in a refrigerator.
2. Apply a thin, even layer of the mixed liquids on both sides of the screen. Let the screen dry completely, away from light and heat. The prepared screen can be stored for up to 2 weeks in the dark until you’re ready to use it.
3. Place a black, high-contrast image on an acetate sheet onto the screen mesh. Position a 150W clear incandescent bulb or photoflood 30cm above the screen. The parts of the diazo not exposed to light will stay soft, while the exposed areas will harden. Exposure times vary from 10 to 90 minutes, depending on screen size and light source.
4. After exposure, remove the unwanted soft emulsion from the screen with a strong spray of cold water or Photo Emulsion Remover. The hardened, exposed photo emulsion will remain on the screen, forming your stencil.
5. You can reclaim the screen using the Photo Emulsion Remover included in the kit when needed.
