How to Prevent Accidental Touch Marks When Using a Pen in Acrobat
Question details
The user wants to annotate PDF documents using an e-pen without leaving unwanted marks from accidental finger or palm touches.

- Product
- Adobe Acrobat
- Device & OS
- Windows (Lenovo Yoga C940)
- Scenario
- Annotating or drawing on a PDF using a stylus or e-pen on a 2-in-1 touchscreen laptop.
- Observed behavior
- Fingers or palms resting on the touchscreen create accidental marks, dots, or trigger gestures while attempting to write with the pen.
Ensure that your e-pen is fully charged and properly paired with your laptop, and that the touchscreen surface is clean to prevent phantom touches.
Enable Palm Rejection in Windows Settings
Since Acrobat relies on the operating system's touch interpretation, enabling Windows palm rejection is the most effective way to ignore hand touches.
Windows has built-in Pen & Windows Ink settings designed specifically to prevent accidental touches when a stylus is detected near the screen.
Click the Start menu and select the 'Settings' gear icon, or press the Windows key + I on your keyboard.
Go to 'Bluetooth & devices' in the left sidebar, then click on 'Pen & Windows Ink' on the right panel.
Expand the 'Additional pen settings' section and check the box that says 'Ignore touch input when I'm using my pen'.

Adjust Adobe Acrobat Touch Preferences
Configure Acrobat's internal settings to optimize how the application handles touch and stylus inputs.
Update Device and Stylus Drivers
Outdated drivers on devices like the Lenovo Yoga can cause poor stylus recognition, leading to palm rejection failures.
Annotate PDFs Smoothly with WPS Office
If you are experiencing persistent touch conflicts in Acrobat, WPS Office provides an excellent PDF reading and editing experience with highly optimized stylus support for seamless annotation.
- 1. Open Your PDF: Launch WPS Office and open your PDF document using the WPS PDF tool.
- 2. Navigate to the Comment Tab: Click on the 'Comment' tab located in the top ribbon menu to access annotation tools.
- 3. Select the Pen Tool: Click on 'Graffiti' or 'Draw' to activate the stylus ink features.
- 4. Start Annotating: Use your e-pen to write directly on the document. The software will focus on your stylus inputs for a smooth writing experience.

Frequently Asked Questions
Why does my palm draw lines when I use my stylus?
This happens when your computer or application fails to activate 'palm rejection'. When the screen detects both the pen and your hand, it may register your hand as a second drawing input unless told to ignore touch input while the pen is in use.
Does Adobe Acrobat have a specific palm rejection toggle?
Adobe Acrobat generally relies on the operating system's native touch API (like Windows Ink) for palm rejection. You must configure palm rejection at the system level via Windows Settings rather than relying on an Acrobat-specific toggle.
How do I turn off touch completely when using a pen?
You can turn off touch input entirely by going to Windows Device Manager, expanding 'Human Interface Devices', right-clicking 'HID-compliant touch screen', and selecting 'Disable device'. You can re-enable it when you finish writing.
Why is Windows Ink ignoring my pen inputs in Acrobat?
Occasionally, driver conflicts or Acrobat updates disrupt Windows Ink integration. Try disabling Windows Ink temporarily in your tablet/pen driver settings, or updating both Adobe Acrobat and your device's pen drivers to the latest versions.
