How to Remove Color Bars and Crop Marks from a PDF
Question details
The user needs to remove commercial printing marks such as crop marks, registration marks, and color bars from a PDF document before printing it.
- Product
- Device & OS
- not provided
- Scenario
- Preparing a PDF file for standard desktop printing without displaying unwanted commercial finishing marks.
- Observed behavior
- The PDF displays crop marks, color bars, and registration marks around the edges of the document, which interfere with standard home or office printing.
Before proceeding, check if your physical printer supports full-bleed or borderless printing, as removing printer marks does not automatically eliminate standard unprinted white margins.
Disable Printer Marks in Print or Export Settings
The most straightforward method to remove commercial marks is to turn off the specific settings in your print or export dialog box.
Crop marks, registration marks, and color bars are typically added during the document export phase for commercial printing purposes. You can easily prevent them from printing by adjusting the settings before sending the file to your desktop printer.
Navigate to the 'File' menu in your PDF viewer and select 'Print', or press Ctrl+P to open the print dialog box.
Look for a section named 'Advanced', 'Marks and Bleeds', or 'Page Setup', depending on the specific PDF software you are using.
Uncheck the option for 'All Printer Marks' or individually deselect the checkboxes for crop marks, color bars, and registration marks.
Verify that the print preview looks clean. Keep your bleed settings intact if your design requires it, and click 'Print'.
Crop the PDF Page to Hide Embedded Marks
If the printer marks are permanently embedded into the PDF content, you can use a cropping tool to remove the edges containing the marks.

Frequently Asked Questions
What is the purpose of color bars and crop marks in a PDF?
They are used exclusively for commercial printing and finishing. Crop marks show the commercial printer exactly where to trim the paper, while color bars help ensure accurate ink density and color consistency across the print job.
How can I print my PDF borderless after removing the marks?
To print without white borders, your physical printer hardware must support borderless printing. You will need to access your printer's system properties through the print dialog and enable the 'Borderless' or 'Edge-to-Edge' printing feature.
Can I remove crop marks from a flattened PDF?
Yes. If the marks are permanently flattened into the document and cannot be disabled in print settings, you can use the 'Crop Page' feature in a PDF editor to trim the outer margins containing the marks, leaving only the main content visible.
Why do I still see a white border after removing all printer marks?
This is the unprintable area defined by your printer's hardware limitations. Most standard desktop printers require a small unprinted margin (usually about 0.25 inches) to physically grip the paper during the printing process.
