Ed, when building blind via boards, some board manufacturers just plate the
vias, rather than plating the lines on the entire external surface. They do
this with a specially designed mask. This "PTH plate only" process allows
better control over the thickness of copper of the lines on boards that
require controlled impedance.
  Hope this helps.
