Question details

Users report that brightly highlighted text in OneNote 2016 becomes opaque and unreadable after exporting a page to a PDF file.

How to Fix Opaque Highlighted Text in OneNote PDF Exports

Product: OneNote 2016 / Office Professional Plus 2019
Device & OS: Windows 10
Scenario: Exporting a OneNote page containing highlighted text into a PDF document.
Observed behavior: The highlight transparency is lost during the export, causing the highlight color to completely cover and obscure the underlying text in the final PDF.

Before you start

Make sure your Microsoft Office 2019 suite and Windows 10 operating system are updated to the latest builds, as Microsoft frequently patches known rendering glitches.

Solution 1Recommended

Use the Microsoft Print to PDF Feature

Bypassing the built-in OneNote export tool and using the virtual PDF printer often preserves highlight transparency.

The native 'Export' function in OneNote 2016 sometimes struggles with alpha channels (transparency) when generating PDFs. Using the Windows 10 'Print to PDF' engine forces the document to render differently, which usually prevents the opaque highlight issue.

Open the Print Menu

In OneNote 2016, navigate to the page you want to save. Click on 'File' in the top-left corner and select 'Print' from the sidebar.

Select the PDF Printer

Click on 'Print'. In the Printer dropdown menu, select 'Microsoft Print to PDF' instead of your physical printer.

Save the PDF Document

Click the 'Print' button. A prompt will appear asking you where to save the file. Choose your destination, name the file, and click 'Save'.

Alternative PDF Printers: If Microsoft Print to PDF also fails, installing a third-party virtual PDF printer (like WPS PDF) can provide better rendering results.

Solution 2

Report the Rendering Issue to Microsoft Support

Because this is a specific software rendering bug in Office Professional Plus 2019, escalating it to Microsoft Q&A can help secure a permanent patch.

Frequently Asked Questions

Why do my text highlights turn into solid color blocks in OneNote PDF exports?

This happens due to a known rendering limitation in certain builds of OneNote 2016 and Office 2019. The export engine fails to process the transparency (alpha channel) of bright highlight colors, flattening them into solid, opaque blocks.

Does changing the highlight color in OneNote prevent it from becoming opaque?

Sometimes. Using lighter, standard highlight colors rather than custom or overly bright shades can occasionally bypass the rendering glitch. However, using the 'Print to PDF' method is a much more reliable solution.

Can I fix the opaque highlights on a PDF that has already been exported?

Once the PDF is generated and the highlights are rendered as opaque, the underlying text is usually permanently obscured or flattened. You will need to regenerate the PDF from the original OneNote page using a different printing or exporting method.
