- Scenario
- Saving or printing a PDF document after filling out a form or signing it.

- The original background of the PDF vanishes, leaving only the newly added text or signature visible on a blank background.
Ensure you have a backup copy of your original, unfilled PDF document before applying updates or testing new software solutions to prevent permanent data loss.
Update PDF Software and Verify File Integrity
Software bugs in specific versions often cause background rendering issues during save or print operations.
Updating your PDF reader or editor to the latest patch ensures you have the most recent bug fixes related to form rendering, layering, and printing.
Open your PDF application, navigate to the 'Help' menu, and click 'Check for Updates'. Follow the prompts to install the latest patch.
Close the PDF editor completely and reopen it to ensure all background services and updates are fully applied.
Open a completely different PDF file, apply a signature, and save it. This helps verify if the issue is a global software glitch or specific to a corrupted document.
If you are trying to print the document, open the Print dialog, click 'Advanced', and select 'Print As Image'. This flattens the file and forces the printer to recognize the background.

Fill and Sign PDFs Safely with WPS Office
Avoid background rendering glitches by using WPS PDF. It securely flattens your signatures and text onto the document, ensuring that your forms save and print exactly as they appear on your screen.
- 1. Open your PDF in WPS: Launch WPS Office and open your PDF document using the built-in WPS PDF tool.
- 2. Access Fill and Sign: Navigate to the 'Fill & Sign' tab on the top ribbon to easily insert text boxes, checkmarks, or your personal signature.
- 3. Apply Your Signature: Place your signature on the document. WPS PDF handles the document layers automatically to preserve the original background perfectly.
- 4. Save or Print: Click 'Save' or press 'Ctrl+P' to print. The flattened document will accurately retain both the visual background and your new inputs.

Frequently Asked Questions
Why does my PDF print blank except for the signatures?
This usually happens due to layered form settings where the background layer is unintentionally set to 'View but don't print'. Changing your print settings to include 'Document and Markups' or choosing 'Print as Image' in the advanced settings can resolve this.
How can I flatten a PDF before saving it to keep the background?
Flattening merges the Fill and Sign inputs permanently with the background layer. You can achieve this by using the 'Print to PDF' feature, which generates a new, unified PDF file where the background cannot be separated from the newly added text.
Does WPS PDF alter the original document formatting when signing?
No, WPS PDF is designed to be highly compatible with standard PDF formats. It maintains the original formatting, form fields, and visual backgrounds without unintentional alterations during the Fill and Sign process.
Is the disappearing background issue specific to Mac or Windows?
This rendering glitch can happen on both Mac and Windows operating systems. It is typically tied to bugs in a specific version of your PDF reader or corrupted form layers within the document itself, rather than the operating system.
