The Preflight panel lets you inspect the contents of a file to ensure it is ready for output.
About the Preflight panel
From the Preflight panel, you can analyze the contents of a file to determine whether it is ready for print or export. The panel reports errors and warnings that are present in your file. From the panel, you can create preflight profiles that specify which error types you wish to check for and how extensive you would like the checking to be.
When a check has been made, the panel displays a list of warnings and errors it has found. The types of errors that are listed are determined by the way the preset has been set up in the panel. Errors are color coded to indicate their severity:
A yellow dot to the left of an entry is a warning of an issue in the file which will not affect export.
A red dot to the left of an entry indicates an error in the file which will interrupt export.
The following settings are available in the panel:
