Personalized signature appearances allow you to provide additional information about yourself, affiliations, or company. Home users often modify the default appearance as a matter of personal taste, while enterprise users are sometimes provided with a company-specific style and logo.
Every aspect of the visible appearance is subject to customization, and the options range from using logos, a replica of your handwritten signature, photos, images, and text. A typical appearance consists of three customizable components:
You can create any number of appearances ahead of time for later use, and the signing workflow allows you to select one from your library of appearances. However, you can also select the default appearance created from your name or create one on-the-fly at signing time. </
When you sign a PDF file, the appearance becomes part of the signed document. It is not part of the signature.
PDF/A is a subset of PDF intended as a file format suitable for the long-term archiving of electronic documents. Appearances in PDF/A-compliant documents must be must conform to the following:
Users generally customize one or more signature appearances and store them for later use. Available signatures are listed in the appearance panel at signing time.

A watermark is a partially transparent graphic that appears “behind” a signature. By default, the watermark is the Adobe PDF logo. Line (vector) art that is simple and unobtrusive often works best.

Illustrator instructions: Set a low transparency level and flatten the transparency:
- Select all and group the objects if there is more than one.
- Choose Window > Transparency and move the slider to some low value such as 20%.
- Choose Object > Flatten Transparency. Leaving the Raster/Vector balance at 100%.
- Save the file as a PDF.
Open the PDF file in Acrobat.
