This last has gotten to be a somewhat contentious issue. I generally
argue that if I send you a PDF version of the drawing with my stamp and
signature which was produced in my office then there is no difference
between that and me sending you via snail mail a print of the original
sealed and signed document. In this case I typically apply "print only"
security to the PDF in order to prevent anyone from copying the seal and
signature electronically. Some jurisdictions require an original signature
on every drawing submitted. That's not too bad if there are only 2-3 sets
of 3-4 drawings, but it's not very much fun if the jurisdiction wants 5
sets of 150 sheets. prints of the sealed and signed original should be
sufficient.

In SW FL the authorities require *wet* seals on every single sheet in every
single set.
I know guys that run 3 or 4 sheets under the seal at a time but sign every
one of them.
