Device & OS

Scenario
Approving or acknowledging receipt of PDF documents with a personalized, time-stamped signature.
Observed behavior
A customized dynamic stamp needs to be generated and applied to automatically capture the user identity and current timestamp directly on the document.
Before you start

Ensure you have access to a PDF editor with form preparation and JavaScript capabilities, as generating a fully custom dynamic stamp requires inserting calculating text fields into a base PDF template.

Solution 1Recommended

Create a Dynamic Stamp Using Adobe Acrobat JavaScript

Use Adobe Acrobat's custom stamp tool and form fields powered by JavaScript to automatically pull the user's identity and system time.

To create a dynamic stamp, you must first design the static elements (like your signature and the words 'Received by') on a blank PDF, and then overlay dynamic form fields that calculate the date, time, and user identity via JavaScript.

1
Create the base design

Design your stamp layout in a program like Word or Illustrator, including your signature and static text. Save this document as a PDF.

2
Add form fields

Open the PDF in Adobe Acrobat, navigate to Tools, and select 'Prepare Form'. Add text fields in the areas where you want the dynamic username, date, and time to appear.

3
Apply JavaScript calculations

Right-click the text field for the date/time, select 'Properties', go to the 'Calculate' tab, and choose 'Custom calculation script'. Enter the required Acrobat JavaScript code to fetch the current date and time.

4
Save to stamps folder

Save this configured PDF file directly into your local Acrobat stamps folder. This registers the file as an available stamp.

5
Apply the dynamic stamp

Open the document you want to stamp, go to the 'Comment' tools, click the 'Stamp' icon, find your newly created custom stamp under the relevant category, and click to apply it.

Scripting Documentation: You may need to review Adobe Acrobat dynamic stamp scripting documentation to find the exact JavaScript syntax for formatting the date, time, and identity objects according to your local preferences.

Frequently Asked Questions

Why is the date and time on my dynamic stamp incorrect?

Dynamic stamps pull the date and time directly from your local system clock. Ensure your computer's timezone, date, and time settings are configured correctly in your operating system.

Can I edit a custom dynamic stamp after applying it?

Once placed, the stamp becomes a single flattened annotation object on the page. You can resize or delete it, but to change the text layout or JavaScript, you must edit the original source stamp file and reapply it.

How do I change the user name that appears on my dynamic stamp?

The user name is pulled from your PDF software's identity settings. In your PDF editor, go to Preferences or Options, locate the 'Identity' or 'User Info' section, and update your First and Last Name.

Do custom dynamic stamps work on mobile PDF readers?

Most mobile PDF readers can display dynamic stamps that have already been applied, but generating a new dynamic stamp containing JavaScript calculations typically requires the desktop version of a premium PDF editor.
