Publish profiles let you:
Save a publish settings configuration, export it and import the publish profile to other documents or for others to use.
Import publish profiles to use in your document.
Create profiles to publish in several media formats.
Create a publish profile for in-house use that differs from the way you’d publish the files for a client.
Create a standard publish profile for your company to ensure files are published uniformly.
Publish profiles are saved at the document rather than application level.
