    Default UV Filter for Flourescent Shop Lights...

    Alright, so the design firm I work for is being gracious enough to let me use a large portion of our basement as a screen printing studio. It's great: tons of space, access to water, no sunlight, decent temperature/humidity, etc. The only problem is that the entire basement is lit by giant flourescent lights that are motion triggered. This means that I can't just turn them off when coating screens. It would cost big $$$ to have the lighting system reprogrammed, so I need to find a work around.

    I took a screen printing workshop a few years ago and I remeber that the coating room and exposure room had flourescent shop lights that had amber-colored "sleeves" over the tubes that blocked out the UV light.

    Anyone know what these "sleeves" are called or where to get them? It's the last major problem I need to sollve before I set up shop...

    I don't know where to find the sleeves,
    but you can use rubylith.
    Also, if you use Ulano QTX, room light is safe.
    You probably want to get some full spectrum buls for color matching.

    I found them here. An they're called "sleeves" - go figure. A bit pricey. I may just get some sheets of UV filter film from the local theatre supply store. It's cheaper and it comes in clear, which would keep me from going nuts in a red or amber basement.

    I wouldn't worry, the amount of UV at 4 or 6 feet even working under them is not going to do anything significant while coating or exposing for a few moments. Regular flourescent won't work in an exposure unit at 3", why would it work at this distance?
    Better to see what you're doing.
    You could drape some ruby over the closest rigs if you are concerned. Or like you said, try the UV film.

    Yeah, I guess I'm being a bit paranoid. Considering I'll be using metal-halide for exposures, the exposure to the flourescents will be insignificant. Thank you both Andys.

    Thanks to you too Steve.

    Hey, completly unrelated to screen printing, check out this site for a good laugh: http://www.mustachemarch.com

    A bunch of people at the design firm I work for are growing mustaches for the month of march. There's a few nice dirtlips in the gallery.

    Those aren't mustaches.
