I would never sign the original vellums. In fact, almost all building
dept. required wet signatures anyway.  Also if you sign the originals
and gave them to the owner or architect who can use them for any other
jobs.  I can smell troubles in the future for wrong details being used.

As I understand it, the lettering of the above says" NEED ONLY" but does
not say "HAVE TO". So it gives you the option of either sign the
originals if you don't want to sign, say 5 copies of the bluelines.
