Fix Data Matrix Barcode Showing as a Gray Box in Acrobat Reader
Question details
The user is unable to view a Data Matrix barcode properly; it renders successfully in the full Adobe Acrobat on Mac but appears as a gray box in Acrobat Reader on PC.
- Product
- Adobe Acrobat Reader
- Device & OS
- PC
- Scenario
- Opening and viewing a PDF form containing a 2D Data Matrix barcode field.
- Observed behavior
- The Data Matrix barcode field fails to render the actual barcode, instead displaying as a blank gray box, even after resizing the field or updating the software.
Verify whether you are currently using the free Adobe Acrobat Reader or the full, paid version of Adobe Acrobat, as their built-in barcode decoding capabilities differ.
Grant 2D Barcode Rights via LiveCycle Reader Extensions
Use Adobe LiveCycle Reader Extensions to embed the necessary usage rights into the PDF, enabling Acrobat Reader to process 2D barcodes.
Two-dimensional barcode fields, such as Data Matrix barcodes, generally do not work natively in Acrobat Reader due to built-in software limitations.
Standard Adobe Acrobat cannot add these specific decoding rights. You must process the document through Adobe LiveCycle Reader Extensions to embed the required rights into the file for Reader users.
Log in to your organization's Adobe LiveCycle (or AEM Forms) server environment as an administrator.
Navigate to the Reader Extensions module and upload the target PDF file containing the grayed-out Data Matrix barcode.
Locate the usage rights settings and select the option to apply '2D Barcode Decoding' rights to the document.
Save the extended version of the PDF. When users open this updated file in Acrobat Reader on a PC, the barcode will render normally instead of showing a gray box.
Open the PDF in Full Adobe Acrobat
Bypass the Acrobat Reader limitation entirely by opening the PDF form using the full version of Adobe Acrobat, which natively supports 2D barcode processing.
View and Manage PDF Documents Easily with WPS Office
Avoid complex rendering errors by using WPS Office. Its robust built-in PDF reader offers excellent compatibility for viewing, editing, and managing standard PDF elements seamlessly across different operating systems.
- 1. Download and Install WPS Office: Visit the official WPS website, download the free version of WPS Office, and follow the straightforward on-screen instructions to install it on your computer.
- 2. Open the Target PDF: Launch the application, select the 'PDF' module from the home screen, click on 'Open', and browse your computer to select your PDF document.

Frequently Asked Questions
Why does my Data Matrix barcode work on Mac but not on PC?
This discrepancy occurs if your Mac is running the full version of Adobe Acrobat, which inherently supports decoding 2D barcodes. If your PC only has the free Acrobat Reader, it lacks the native capability to decode them without specialized embedded rights.
Can I use standard Adobe Acrobat to add 2D barcode rights?
No. Standard Adobe Acrobat software cannot embed 2D barcode usage rights into a PDF. You must use Adobe's enterprise solution, LiveCycle Reader Extensions, to append these specific capabilities to the file.
Will resizing the barcode field fix the gray box issue?
No. Resizing the barcode field will not resolve the gray box error in Acrobat Reader. The issue stems from missing software licensing and decoding rights within the document, not the physical dimensions of the form field.
Are 2D barcodes completely unsupported in Acrobat Reader?
Acrobat Reader can display 2D barcodes, but only under the strict condition that the document creator has previously granted and embedded '2D Barcode Decoding' rights into that specific PDF using Adobe LiveCycle Reader Extensions.
