How to Fix a Custom Exhibit Stamp That Does Not Work in Acrobat XI
Product
Adobe Acrobat XI
Device & OS
not provided
Scenario
Applying a custom legal exhibit stamp to a PDF document.
Observed behavior
The custom exhibit stamp is successfully installed in the Stamps folder, but its name and content remain locked and cannot be edited after placement.
Before you start

Ensure you have the original download package from the stamp provider, as it may contain accompanying folder-level JavaScript (.js) files necessary for dynamic editing features.

Solution 1Recommended

Install the Accompanying Folder-Level JavaScript

Dynamic exhibit stamps require a specific background script to function properly and allow editing after placement.

Many downloadable legal exhibit stamps are dynamic and rely on JavaScript to prompt the user for input or to allow name editing. If only the PDF stamp file was installed without the corresponding script, the stamp will behave as a flat, uneditable image.

1
Locate the script file

Open the stamp package you downloaded and locate the attached folder-level script, which typically ends in a .js file extension.

2
Copy to the JavaScripts folder

Navigate to the Acrobat XI installation directory and copy the script file directly into the application's 'JavaScripts' folder.

3
Restart the application

Close and reopen Adobe Acrobat XI to initialize the new folder-level script and unlock the stamp's editing capabilities.

Install the Accompanying Folder-Level JavaScript
Installation Verification: Once restarted, apply the stamp to a blank PDF document. You should now be prompted to edit the stamp's text or properties.

Frequently Asked Questions

Why can't I edit my PDF stamp after applying it?

Dynamic stamps require a specific folder-level JavaScript file to allow editing. If this script is missing from your software's JavaScript folder, the stamp will behave as a flat, static image and cannot be modified.

Where is the Stamps folder located for custom PDF stamps?

The Stamps folder is typically found in your system's AppData directory under Roaming > Adobe > Acrobat > [Version] > Stamps. Placing custom PDF files in this directory allows the application to read them as stamp tools.

Is Adobe Acrobat XI still supported?

No, Adobe Acrobat XI reached its end of life several years ago and no longer receives security patches or feature updates. Upgrading to a newer, actively maintained PDF editor is highly recommended.
