Well, not sure if drilling first will work or not, my idea was to print drill pattern on thin paper so holes 'n vias could be seen from back side, put TT paper on one side of PCB, run thru laminator once to stick paper in place. That would cause the drill pattern of all holes to be visible, then drill thru this thin paper.

With all the holes drilled, I was hoping lining up both sides of TT paper to the existing drilled holes would improve hole registration. Currently my double sided boards have most of the traces on one side, with only a few on the other side. This keeps the holes to a minimum.

As I write this, I'm not sure it will work - maybe I'll get to try later this week.
