Wish I could answer your question but I have no expererience at all in using pin registration systems with vacuum frames. Maybe someone else can offer some advice.

I have a Condit contact frame packed away somewhere and I believe the pins are glued to the surface of the glass and the surface onto which the paper and negatives\masks are placed is a little spongy.
Do you think I'll be able to do this with the ULF-28? I think pin registration was one thing that maybe wasn't considered in the units' design, was it? I anticipate that masking for contrast control may be a big part of printing my 12x20 negatives.
