You’ve created your final PDF.  Even though it should look just like the document you’ve been working on for months now, it’s worth paging through the PDF to make sure that all your formatting has been preserved, as certain PDF creation tools might have subtly changed your line spacing, for instance, which can have a dramatic effect on the final product.  Have a close look at the graphics.  Do they appear as intended? 

That visual inspection is a good first step.  But PDFs are complicated.  It’s also worth looking a bit at what’s happening inside, particularly with the fonts.
We recommend that your PDF have all embedded fonts.  There are several reasons for this:
  1. Font embedding is required to meet archival standards
  2. If a font is not embedded, and the document is opened on a computer that doesn’t have that font, substitution will take place. This might change the look and format of the document.
  3. A PDF without embedded fonts cannot be printed at a professional printer.
  4. If a font is not embedded, we will attempt to embed them.  Not all fonts with the same name are identical; minor changes might be introduced.
  5. If we can’t embed the font, we will create hi-resolution image of the page if the document is to be printed.  No image, of whatever resolution, will print as crisply as a native PDF page.
Here’s how to check to see if your fonts are embedded:
  1. Open your PDF in Adobe Acrobat Reader (available for free at https://get.adobe.com/reader/).
  2. Go to File-->Properties-->Fonts.
  3. The program will list all the fonts that you’ve used in your document. 
  4. After each font, you should see “(Embedded)” or “Embedded Subset).”  If the name of the font is not followed by one of those notifications, the font is not embedded.
Here’s an example of what you might see in the Fonts tab of the Properties menu:

In this example, we can see that there are font embedding problems.  The font TimesNewRomanPS-BoldItalicMT is not embedded. The remaining fonts, however,  are embedded, either completely or as a subset.
