Translucent? Or do you mean transparent background? I've made all the sigs with a transparent background but it's tough to get them just right.
The whole thing is laughable really. Give me a solid digital signature any day of the week over the security of a photoshopped signature. But it's tough to explain that to folks.
For example, my doc has been frustrated that he can't sign labs after they've been imported. Well, that's because I can't figure out how to make AC use pdf annotator to view pdfs instead of Adobe. He figured the pen icon was just broken in AC. I had previously set up pdf annotator so the medical staff can DRAW on the labs (before they're imported), which they LOVE, because they can do things "the paper way." When the lab is imported to the patient chart, the documentation is easily visible.
BTW, if anyone knows how to put annotator into AC as the default pdf viewer, I'd love to know how
