How to Fix Random Thick Lines in FrameMaker PDF Tables
Question details
User needs to eliminate randomly thick lines that appear in PDF tables exported from FrameMaker, which seem to shift in thickness when zoomed.
- Product
- PDF Viewer
- Device & OS
- not provided
- Scenario
- Reviewing a PDF file containing tables that was recently exported from Adobe FrameMaker.
- Observed behavior
- Table lines and borders appear inconsistently thick on the screen, and the thickness of the lines fluctuates when adjusting the zoom level.
Before altering any software settings, print a test page of the affected PDF table. If the printed lines appear normal and consistent, the issue is purely a screen rendering artifact and your source file is perfectly fine.
Disable the Enhance Thin Lines Display Option
Turn off the anti-aliasing display feature in your PDF viewer that artificially thickens thin lines to make them more visible on screens.
The inconsistent line thickness you are seeing is a visual artifact caused by the PDF viewer's display settings, rather than an error in your FrameMaker document.
By disabling the line enhancement feature, the PDF software stops applying anti-aliasing to borders, allowing you to view the true line weights of your exported tables.
Launch Adobe Acrobat or Adobe Reader. Go to the 'Edit' menu at the top (or the 'Acrobat' menu if you are on a Mac) and select 'Preferences'.
In the Preferences window, look at the Categories pane on the left side and click on 'Page Display'.
Locate the 'Rendering' section on the right side. Find the checkbox labeled 'Enhance thin lines' and uncheck it.
Click the 'OK' button at the bottom of the window to apply your changes. Check your PDF table again to confirm the lines are rendering evenly.
Read and Review PDF Tables Flawlessly with WPS PDF
If you frequently encounter display glitches with complex documents, use WPS PDF to view your exported FrameMaker files. WPS Office offers a highly capable PDF reader that accurately renders line weights and tables without distracting visual artifacts.
- 1. Download WPS Office: Download and install the free WPS Office suite from the official website onto your computer.
- 2. Open Your PDF: Launch WPS PDF and open the PDF file you exported from FrameMaker.
- 3. Review the Document: Scroll through your document and adjust the zoom levels to enjoy accurate, artifact-free rendering of your tables and line weights.
Frequently Asked Questions
Why do PDF table lines change thickness when zooming in or out?
This happens due to a display rendering technique called anti-aliasing used by many PDF readers. The software attempts to make very thin lines visible on computer monitors by artificially thickening them, which scales dynamically and unevenly as you adjust your zoom percentage.
Will the thick lines show up when I print the PDF?
No. If the thick lines are caused by the 'Enhance thin lines' viewing setting, they are only a screen display artifact. The printed document will respect the exact line weights specified in your original FrameMaker file.
Can I fix the line thickness in FrameMaker before exporting?
The issue originates from the PDF viewer's display settings, not the FrameMaker export itself. However, applying a slightly thicker, uniform stroke weight (such as 0.5pt or 1pt) in your FrameMaker Table Designer can sometimes minimize the visual discrepancies caused by screen rendering.
Does this rendering issue occur in all PDF viewers?
Not all PDF viewers enhance thin lines by default. This is primarily a well-known default behavior in Adobe Acrobat and Adobe Reader. Other PDF viewing software, such as web browsers or WPS PDF, use different rendering engines and may display the lines accurately by default.
