You can use Speedball Diazo Photo Emulsion with a photo sensitizer to make stencils on a screen printing mesh for detailed images like film positives and drawings on acetate film. Here’s how it works:

  1. Coat the screen with the sensitized emulsion and let it dry in a dark room.
  2. Place your image on the screen, positioning it below a UV light source, such as a bulb or sunlight.
  3. The emulsion under the dark, opaque parts of the image will stay water-soluble, while the exposed areas will harden.
  4. The hardened emulsion now acts as a stencil, preventing ink from passing through the screen mesh.
  5. After using the screen, it’s important to reclaim it promptly. Start by cleaning away any ink residue using a soft brush, water, and detergent.
  6. Next, remove the exposed emulsion using an emulsion remover.

This process allows you to create and reuse stencils for screen printing.
