After a bit of research I solved this problem. I asked a few other labs what they did and a couple said they just used an image. I signed a sheet of paper and scanned it into my PC. Then I cut and pasted it into paintbrush and deleted all the fill so only the lines of the signature remained. I just import the image in Excel and paste it into my signature boxes in my spreadsheet templates.
Depending on how far the applicable regulatory requirements go, you can also create a self-signed certificate within Acrobat and then use Adobe's "Sign with digital certificate..." option. It creates an additional Adobe-generated, password-protected imprint and the option to lock the document. It's pretty easy to do in Acrobat 10+, a little more opaque in the older versions. I have to do this fairly regularly as an engineer, since many states now accept digitally seal-signed documents provided there is a means of locking the document against further edits (a maddeningly inspecific requirement, but the Adobe method is widely used and has never raised complaints).
I use an imported image for my state-issued stamp and signature, and the Adobe certificate to finalize the document.
