You can set the appearance of your digital signature by selecting options in the Security Preferences. For example, you can include an image of your handwritten signature, a company logo, or a photograph. You can also create alternate signature appearances that you use for different purposes. For some, you may want to provide a greater level of detail.
A signature appearance can also include information that helps others verify your signature, such as certificate revocation status, reasons for signing, contact information, and more. By selecting these preferences, you add options to the Sign Document dialog box that appears each time you sign a PDF.
