How LaTeX writes PDFs

  • • pdfTeX embeds Type1 fonts such as Computer Modern.
  • • Kerning and ligatures are written into each line.
  • • Equations are built from many small pieces.

What that means when you add a watermark

  • • Body text and headings edit well; kerning is preserved around your change. Equations are best changed in the source and recompiled.

What happens to the rest of the page

  • • The watermark is added as a layer; the original page content is not rewritten.
  • • Works on every page at once.

Questions people ask

+Can I remove a watermark later?

Keep the original file. Watermarks are added to the copy you download.

+Is it better to edit in LaTeX?

If you have the original LaTeX 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.
