- What is this unit used for?
- It exposes photo-emulsion screens and plates: small-screen stencils, printing screens, transfer steel plates and hot-stamping dies. The 395nm UV light hardens the emulsion where the artwork lets it through.
- Does it work with standard screen printing emulsion?
- Most diazo and dual-cure emulsions are sensitized to UV around 395nm, so the wavelength fits. Exposure time depends on emulsion, mesh and coating thickness, so run a test strip first.
- Is there a vacuum frame to hold the film flat?
- No. The unit relies on the screen and film being pressed together, usually with a weight or glass. Gaps between film and emulsion cause light undercutting and soft edges.
- What comes in the box?
- The exposure unit and a blackout cloth for blocking stray light. You supply the screen, emulsion, film and any glass or weight used to hold contact.
- How long do exposures take?
- Expect several minutes per screen with a 60W lamp, longer than with high-wattage multi-lamp units. Test with a step exposure to find the right time for your emulsion.
