Adobe Acrobat 7 Professional - Manual (Page 618)

About preflight profiles
Acrobat includes several predefined preflight profiles, which you can use as is or modify
to create custom profiles. The rules that make up the profiles are organized by categories.
Each rule in a category governs a particular document property.
To help you determine what document properties the preflight profile analyzes--and thus
how to set parameters--you can review information about each selected rule in the Edit
Profile dialog box. This information describes what criteria the rule uses to analyze a
document property.
For detailed information on the components of a preflight profile, see About rules and
conditions and About property groups .
