Rob,
Have you considered carbon ink in place of the gold? We have been using carbon ink for several years (MUCH more cost-effective than selective NiAu plating), and and our customers have been very satisfied with the results. I don't know, however, about how carbon ink cost would compare with Alpha Level.
