The Fonts, Text & Strokes section protects text integrity. Missing or unembedded fonts are the number-one preflight failure, because text that isn’t carried in the file can’t be guaranteed to print correctly. Each check lists its action, settings, and the messages the customer sees. See the profile overview for how actions work.
