How to make a light table
Madeline Donahue and Josh Copp build a light table (known to the pros as an exposure unit) out of stuff from the hardware store so they can burn silk screens at home. Feel free to use this as inspiration to build your own. The electrical stuff can be dangerous, so if you’re not comfortable with wiring up the lights yourself, get some help just to be safe.

The glass is about a 1/4″ thick. We got two 1/8″ thick panes at Home Depot and put them on top of each other so the glass would be stronger and thicker. They didn’t have a great glass selection so we improvised.

We chose the fluorescent bulbs available at our local Home Depot and Lowe’s- really, you can use any variety of fluorescents just be sure to evenly distribute the light. Pick the same wattage- ours are 20 watt per bulb. You don’t want a bulb too strong because it will burn too much and unevenly.
are those ordinary …
are those ordinary flourocent bulbs or are special??
exposure time is …
exposure time is based on many factors:
1. screen mesh count
2. emulsion sensitivity (different emulsions have different sensitivities.)
3. UV concentration of light source.
4. distance of light source from screen.
5. emulsion coating thickness
6. art material used: transparency expose faster than translucency. other factors (humidity) can affect as well.
I use Saati Textil PV & 500 watt halogen work light. new bulb 13 inch distance exposes 110 mesh/transparency in 2 to 2.5 minutes.
