Our DIY UV Screen Exposure Bulb is a great way to expose emulsion for an economical price. This CFL UV Fluorescent Bulb is specifically manufactured for Ryonet and not available on the market anywhere else. Simply screw in the bulb to any light fixture and safely expose a screen with the recommended WBP Dual Cure Emulsion for 10-11 minutes in a light safe environment.
Tech Specs:



  • Electrical: 110v 25W 60 Hz
  • Mount: E27 Base
  • UV Wave Length: 360-380nm




To Expose A Screen:

  1. Source a light fixture to power bulb.
  2. In a light safe environment center bulb directly above the middle of the screen at a height of 12-15 inches. Note: The higher your bulb is, the longer your exposure time, and the more coverage to the screen. The lower your bulb is, the shorter your exposure time, but the more direct your light source is to the center of the screen. For larger screens use a higher distance and increase exposure time.
  3. Place opaque black transparency reverse onto shirt side of screen and tape to screen. If your transparency is not opaque your screen will not expose as well. We recommend using Ryonet’s Waterproof Rite-Film and Blackmax Ink powered by AccuRIP for maximum density. Rite-Film will also work with standard Epson printer ink. Use BEST QUALITY PHOTO and PREMIUM GLOSSY PHOTO PAPER settings in your print driver.
  4. You can add a piece of thin optically clear glass on top of your screen to increase the positive pressure during exposure. This is optional but will increase the detail gained during exposure.
  5. Expose for 10-11 minutes in a light safe environment. Note: Ensure your screen is bone dry before exposing, we recommend drying and exposing in a room under 40% humidity. The more emulsion your screen has, the longer your exposure times will be. Increase exposure for lower mesh counts.
  6. Exposing with RyoCap: Expose for 3:45-4 minutes (depending on mesh) in a light safe environment. Note: Ensure your screen is bone dry before exposing, we recommend drying and exposing in a room under 40% humidity. If your screen washes out too easily, increase your exposure times slightly. If your image has a hard time rinsing out, decrease your exposure times slightly. 
  7. Washout your screen in a light safe environment.
Exposure Tips: 

    • If your image does not expose or washout properly.

      • First ensure you are in a light safe environment.

      • Ensure your screen is coated with a thin coat of emulsion and allowed to dry so it is smooth to the touch. If your emulsion is tacky you need to either coat it with less emulsion or dry it for a longer period of time. You can use a clean fan or dehumidifier to speed up the drying process.

      • Ensure your film positive is dark.

      • Ensure your screen has positive contact between the film positive and the screen mesh. Add a sheet of glass or foam under the screen to increase positive contact.

      • If your screen exposes but is slimy, increase exposure time by 1 minute and try again.

UV Light Notice: This bulb emits UV Light. Eye protection should be used during this process.  Always use proper precautions to be safe. Prolonged exposure directly to eyes or skin will cause damage. Keep out of reach of children.
