    Default Screen help-

    so i just exposed three screens and had the same problem on all of them, a problem i have not had before.

    1st of all, it seems like the emlution on the inside of the screen on all of them blew out, while retaining the stencil on the other side. So the stencil still was fine on one side, but almost non-existant on the other.

    2nd- it seems as though the emlution that was being washed out was exposing as i washed it out. (like one side to the other) I was flipping sides as i rinsed, and i was using a very light spray.

    ideas?, especially on the first problem.

    HI Ed....my guess....Under exposed.

    As the UV light goes through the stencil material from the bottom surface to the top, it gradually exposes the stencil in layers as it penetrates. The stencil closest to the light source is totally cured and hardens.

    You either need a stronger light, longer time, or move it closer, or all three.

    This effect (the top layer coming off during washout) is common and ok if you wash it all off and still end up with stencil encapsulating the mesh. When you have a sticky screen surface after washout, that's partially exposed stencil material left behind. Turns into scummning (dried in blockages) if you let water drip down during the drying or it rewets while printing with WB and clogs your screen.

    it was indeed too short exposure. I left it in for another 10 seconds and it worked well. Thank you mr.squeegee sir.
