Converting PDF to PDF/X-3

PDF Studio has the ability to convert files in the PDF/X-3 format. PDF/X-3 is a strict subset of the ISO PDF specification with a series of printing-related requirements which do not apply to standard PDF files. These are done with the intent that the document will print exactly the same as when they were saved. PDF/X-3 accepts calibrated RGB and CIELAB colors, while retaining most of the other restrictions of PDF/X-1a.

When converting to PDF Studio will attempt to convert the PDF to the PDF/X-3 format by making the following changes to the document

  • Colors and/or Color Spaces of Vector (paths and text) and raster (images) graphics objects may be converted to be compatible with the PDF/X Output Intent's color profile
  • Fonts will be embedded
  • Transparency will be removed
  • Annotations may be removed or flattened
  • JavaScript (mostly used in Forms) will be removed
  • Image encoding / compression types may be changed

 

How to Convert a PDF to PDF/X-3

  1. Open the PDF Document you wish to convert
  2. Go to the Convert Tab > PDF/X > PDF/X-3 on the menu
  3. A dialog will be displayed showing the changes that will be made to the document
  4. Choose a file name and location to save the document
  5. Click Save to convert the document to PDF/X-3

    If any problems occur during preflight conversion, a results list will be displayed showing the content items that could not be fixed. If the conversion completes successfully the problems list will not be shown and the newly converted document will be opened.

PDF/X Conversion Results

PDF Studio will attempt to convert every file but due to the PDF/X-3 requirements some files may not be able to be converted. If the conversion fails a dialog will be displayed showing the reasons that the conversion failed.

Results List - Lists any content in the document that was not converted with the selected profile.

 - Items that could NOT be fixed by PDF Studio.

 - Items that were not fixed due to user settings in PDF/X Preferences.

Expand - Expands the results tree to show all preflight error results

Collapse - Collapses the results tree to only show the preflight error categories

Print - Prints the entire tree exactly as it is displayed in the preflight results list

Note: When the conversion is successful no dialog will be displayed as the conversion process completed and saved the new document correctly
