If you wanted to add more information to a PDF document without altering the content too much, adding a stamp might be your best option. Adding a fillable, customizable, and dynamic stamp can give the document that extra added padding needed to include additional information or validate the content. It can be very difficult to do so. This comprehensive guide will show you how to create a stamp in Adobe Acrobat and a better alternative.
What is a Dynamic Stamp in Adobe?
Adding a stamp to a PDF is much like applying a rubber stamp to a paper document. And just as you would have different kinds of rubber stamps to signal different things on a physical document, Adobe Acrobat gives you a variety of stamps to choose from. You can even create your own stamps that are unique to your business or organization.
A Dynamic stamp in Adobe is a type of stamp that is designed to get data from your computer as well as from the identity panel of the Preferences dialog box. In this way, the Dynamic stamp can have accurate name, date, and time information.
How to Create a Custom Dynamic Stamp in Adobe
To create a custom dynamic stamp using Adobe Acrobat, use the following steps;
Step 1: Open Adobe Acrobat on your computer. This feature may not be available on the free online version of Acrobat. So, you may need to purchase and install Adobe Acrobat on your computer.
Step 2: In Acrobat, click on "Tools" and select "Stamp".

Step 3: The Stamp Window will open. Here, click on "Custom Stamps" and choose "Create."
Step 4: Now click on "Browse" to choose a stamp image from the file types that you will see in the "Open" dialog box. Click "OK" when you've made your selection and the file you have selected will be converted to PDF.
Step 5: This will take you to the "Create Custom Stamp" window. Here, chose "Dynamic" in the category, name the stamp, and click "OK."

Step 6: Now find the newly created stamp on your computer and open it. The file will be located in the following paths:
- PC: C:\Users\[user name]\AppData\Roaming\Adobe\Acrobat\DC\Stamps
- Mac OS: /Users/[user name]/Library/Application Support/Adobe/Acrobat/DC/Stamps
Step 7: Now go to "Tools" and click "Prepare Form." Ensure that the stamp you have just created is selected and then click "Start."
Step 8: Click on "Add a Text Field" and then name and place the field where you would like the date to appear.

Step 9: Double-click on the text field and choose "All Properties."
Step 10: Click on the "Calculate" tab and choose the "Custom Calculation Script." Click "Edit" to open the JavaScript Editor window.
Step 11: Type in the code below in the JavaScript Editor and click "OK."
event.value = util.printd ("h:MM tt, mm dd, yyyy" , new Date);
Step 12: Now close both the "Text Field Properties" dialog and the "Prepare Form" mode and save the file. You might want to rename the stamp so it is easier to find later.

Now your Dynamic Stamp will be ready to use on any computer, just copy the file to transfer it whenever you need to add it to your document.
Disadvantages of Using Adobe to Create a Stamp
A Dynamic Stamp like the one you can create using the steps above can be very useful in numerous ways, especially since it can validate the date and time that the stamp was added to any PDF. But Adobe doesn't make it very easy to create a PDF stamp.
In our tests, we found that there are several disadvantages you will have to contend with when attempting to create a stamp in Adobe Acrobat. They include the following;
- The process to create the stamp is complicated and it is very easy for something to go wrong in the implementation. We had to try more than once to get the date and time right and you may find that you will as well, thereby wasting valuable time.
- This feature is not available on the free version of Adobe Acrobat. To create a Dynamic Stamp, you have to purchase the full version of Acrobat which can be quite expensive.
- We also found that Acrobat can be slow to load large PDF files which was certainly a problem for us when we tried to add the stamp in numerous locations on the document.
