- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Grading digital academic papers and adding handwritten annotations to PDFs using a drawing tablet.
- Observed behavior
- The user needs to ensure their Wacom tablet, drivers, and operating system are compatible to successfully use pen input and drawing tools in the software.
Before beginning, ensure your Wacom tablet is properly connected to your computer via USB or Bluetooth and that the device is adequately charged.
Install Wacom Drivers and Use Acrobat Comment Tools
The most critical step is ensuring the correct Wacom drivers are installed so Acrobat recognizes the pen input for drawing and handwritten annotations.
To effectively use your Wacom tablet for grading, both the hardware and the software must be properly configured to communicate with each other. Without the official drivers, your computer may treat the tablet as a generic mouse, disabling smoother drawing capabilities.
Visit the official Wacom website, locate your specific tablet model (such as the Intuos family), and download the latest drivers for your operating system.
Run the driver installer, follow the on-screen prompts, and restart your computer to ensure the driver initializes correctly.
Launch Adobe Acrobat and open the digital paper you need to grade.
Navigate to 'Tools' and select 'Comment'. Click on the 'Draw free form' tool (the pencil icon) from the annotation toolbar.
Use your Wacom pen to write directly on the document. You can adjust the line thickness and color from the properties bar for easier reading.

Grade Papers Easily with WPS Office PDF
WPS Office offers a built-in PDF editor with robust freehand drawing and annotation tools, making it incredibly easy to grade papers using your Wacom tablet or any stylus.
- 1. Open the document in WPS PDF: Launch WPS Office and open the PDF file you wish to grade.
- 2. Access the Comment tab: Navigate to the 'Comment' tab on the top ribbon.
- 3. Select the Graffiti tool: Click on 'Graffiti' or the freehand drawing tool to activate pen input.
- 4. Customize your pen: Choose your preferred ink color and line thickness for grading.
- 5. Grade with your Wacom tablet: Use your stylus to write comments, draw shapes, and grade directly on the document.

Frequently Asked Questions
Why isn't my Wacom pen drawing smoothly in Adobe Acrobat?
This usually happens if the Wacom driver is outdated or conflicting with another driver. Try updating your Wacom driver from the manufacturer's website and ensure 'Windows Ink' is enabled in the Wacom Tablet Properties if you are on a Windows OS.
Can I use the eraser end of my Wacom pen in Acrobat?
Acrobat's support for the hardware eraser varies. If it doesn't automatically erase, you may need to manually select the 'Eraser' tool from the Comment toolbar or map a pen button to the erase function in the Wacom Tablet Properties.
Are Wacom Intuos models compatible with all PDF editors?
Generally, yes. Wacom Intuos tablets act as standard pointing devices, so they work with most software. However, advanced features like pressure sensitivity depend on the specific PDF editor's capabilities and the proper installation of Wacom drivers.
