Hi,
We put a paste on our global fiducials but ask the stencil vendor to
half etch them (ie from one side only) on the non-squeegee side and half
fill them with black ink.
This enables the stencil to be aligned, using the fiducials (don't ask
me how), but puts no paste on the board.
Incidentally, we put our part number and other details in half etch also.
None of our stencil suppliers have ever had a problem doing this. They
are clever enough to recognise global fiducials without having to
include them in a drawing.
Cheers, Dave
