I'm creating a form with Adobe X Pro that requires a signature, but a majority of the people i will be sending this form to will likely only have adobe reader. Is there a way for them to "place an ink signature" or sign it with adobe reader?
There are two types of signatures that Adobe Reader can apply.
1. The Digital Signature requires a Reader-extended document via Adobe Acrobat Pro or LIveCycle Server ES4 and a pre-created Signature field in the document.
2. The Electronic Signature which is applied through an online service called Adobe EchoSign and which is a paid service.
You need to decide which one you want your users to use and then proceed accordingly.
Starting with Adobe Reader 11.0.7 you can apply digital signatures in Reader in PDFs that are not Reader-extended.
