Ground Controls->Non_PDF->Fonts->Status
Inactive Fonts - This Ground Control will trigger if any font referenced in the document is not active on your system. Please note that a referenced font does not mean that the font is actually used in a document. The classic example of this is a font referenced because it is part of a style sheet and that style sheet is not used in the document. Typically instead of this Ground Control you will want to use the "Inactive Used Fonts" or "Missing Used Printer Fonts" or "Missing Used Printer Fonts".
Inactive Used Fonts - This Ground Control will trigger if a font actually used in a document is not active on your system. This will only be a problem if you need to edit or print a document. If you are merely seeing if all fonts are present for a job, then FlightCheck can still find and report on inactive fonts as long as you have set up your Font Database properly. Please see setting up and using the fonts database.
Missing Screen Fonts - This Ground Control will trigger if FlightCheck cannot find a referenced Screen Font. Most people will prefer to use "Missing Used Screen Fonts".
Missing Used Screen Fonts - This Ground Control will trigger if FlightCheck cannot find a Screen Font detected as being used in document. Screen fonts are the bitmap portion of PostScript fonts and when missing may cause fonts to image improperly on screen. This can be an issue if you use soft proofing.
Missing Printer Fonts - This Ground Control will trigger if FlightCheck cannot find a referenced Printer Font. Most people will prefer to use "Missing Used Printer Fonts".
Missing Used Printer Fonts - This Ground Control will trigger if FlightCheck cannot find a Printer Font detected as being used in document. Printer fonts are the vector portion of PostScript fonts and when missing cause fonts to image improperly on final output to plate or film.
Embedded Fonts - This Ground Control will trigger if a font is detected as Embedded in a document. Embedded fonts may cause issues if someone tries to do a last minute edit of a document and they do not have the actual font that is embedded installed and active on their system. Embedded fonts may essentially prevent last minute editing of jobs. FlightCheck does not collect embedded fonts, but it does flag them as embedded in the Collect Window. By default Adobe Illustrator embeds fonts into EPS files. If you want to collect fonts used in EPS file then you may want to consider changing the setting in Illustrator to link to fonts instead of embed them.
Corporate Fonts - This Ground Control will trigger if you added any font names to the Corporate Fonts list and the fonts are detected in the document but are not on your list. Corporate Fonts can be quite useful if you require a specific set of fonts for say a corporate identity and you want to be warned if someone uses a font that is not on your approved list of fonts.
