Fix PDF Printing with Black Text Shadows and Artifacts
Question details
The user needs to resolve an issue where PDF documents print with black text accompanied by shadows or visual artifacts, while Microsoft Word and Excel documents print normally.

- Device & OS

- Scenario
- Printing PDF documents.
- Observed behavior
- Printed PDF pages exhibit black text shadows, ghosting, or unexpected artifacts, which may be caused by color cartridge misalignment, outdated drivers, or specific PDF rendering settings.
Verify your printer's ink or toner levels and run a standard printhead alignment test to rule out basic hardware failures before modifying your PDF software settings.
Isolate the Issue and Troubleshoot Hardware Cartridges
Determine if the shadow effect is caused by a hardware issue, such as a leaking or misaligned color ink cartridge.
Even when printing black text, some printers mix color ink to create a richer black. If a color cartridge is faulty or misaligned, it can create a shadow effect behind the text.
Print a standard document containing black text directly from Microsoft Word. If the shadows appear here as well, the issue is hardware-related.
In your printer properties dialog, select 'Print in Grayscale' or 'Black Print Cartridge Only' and print the PDF again. If the shadow disappears, your color cartridge is the culprit.
Access your printer's maintenance menu via its built-in screen or desktop software, and run the 'Clean Printheads' and 'Align Cartridges' utilities.
Adjust PDF Software Security Settings
Modify rendering and security settings within your PDF reader to resolve software-side printing glitches.
Use the Print as Image Option
Bypass complex font and vector rendering errors by sending the document to the printer as a flat image.
Print PDFs Smoothly with WPS Office
Use WPS PDF to quickly open, manage, and print your PDF files without rendering glitches. It offers built-in advanced printing options, such as 'Print as Image', which easily bypasses complex formatting issues and eliminates unexpected text shadows.
- 1. Open PDF in WPS Office: Launch WPS Office and open your problematic PDF document.
- 2. Access the Print Menu: Click the 'Print' icon on the top toolbar or press Ctrl+P.
- 3. Select Print as Image: In the print dialog, locate and check the 'Print as Image' option to bypass font rendering.
- 4. Print the Document: Click 'Print' to output the document cleanly without text shadows.
Frequently Asked Questions
Why do PDFs print with shadows when Word documents do not?
PDF files use entirely different rendering engines for fonts and vector graphics compared to standard word processors. If the printer driver interprets the PDF's specific color space or font layering incorrectly, it can create a shadow effect during printing.
How can I tell if my ink cartridge is causing the text shadows?
Force your print job to use 'Grayscale' or 'Black Print Cartridge Only' via the printer properties menu. If the shadows disappear when color is disabled, your color cartridge is likely misaligned, leaking, or depleted.
What does the 'Print as Image' setting do?
The 'Print as Image' setting bypasses standard text and vector processing by converting the entire PDF page into a single, flat picture before sending it to the printer. This avoids misinterpretations by the printer driver and often resolves complex rendering artifacts and shadows.
Can outdated printer firmware cause PDF printing issues?
Yes, outdated printer drivers or firmware might struggle to process modern PDF encoding or layered security features correctly. Updating to the latest firmware from your printer manufacturer's official website can resolve these compatibility bugs.
