How Adobe InDesign writes PDFs

  • • Fonts are embedded as subsets, often OpenType CFF.
  • • Text frames can be threaded across columns.
  • • Precise kerning and tracking are written into lines.

What that means when you underline text

  • • Kerning and tracking are kept around your edit. Many InDesign fonts are commercial, so new letters come from the PDF or, with your permission, a close open font.

What happens to the rest of the page

  • • The underline follows the text's colour and position.
  • • Underlines move with their words when text reflows.

Questions people ask

+Can I remove an underline?

Yes. Select the words and press U again.

+Is it better to edit in Adobe InDesign?

If you have the original Adobe InDesign file and a lot to change, yes. For quick changes to the PDF itself, editing the PDF is faster and keeps it exactly as sent.
