    Default Dual Light Sources

    The exposure rig I've used forever is an overhead-suspended light rig containing 2 500 watt halogen units with the glass removed from each. The bulbs in the units are like 8 inches apart. See attached pic of it hanging in-place above the table I use to expose the screens and print on.

    I had someone recently tell me that I need to ditch one of the lights because with 2 sources, there's a greater chance of light undercutting when exposing.

    What say you all?

    I say that that's some beautiful workspace.

    Light is both a particle and a beam.

    Technically true, but a single source fairly close like that will also undercut due to the light striking parts of the screen at an oblique angle. An ideal setup would have a single source, far away. And for that to work, you'd need a light that was bright as fuck.

    Keep your positive tight to your mesh, and your setup should be fine for most uses.
    A little undercutting will be a problem for fine halftones, and not much else.

    "it just seems like so little effort is put into creating this? am i missing something?"

    Thanks dude. Building it almost bankrupted me, but it's like I wanted it. Really a creative space... I sleep upstairs in the loft and work downstairs. Hardly ever leave except to fetch beer.

    Yeah... that's what I thought. Thanks for the input. My stuff never has halftones anyway. More like 5th generation photocopies, so it's very forgiving. lol

    Think I'll hook them both up again and do some testing tonight.

    Thanks again,

    You guys rock. I'm well into my third beer and think I'm ready for a test burn.

    Stay tuned.
