Since Version 7 Acrobat has a built in preflight function (in the Professional version of the software). While this function can never be as smart as an operator, it makes it easy to check for frequent problems such as missing fonts, low resolution pictures and excessive colours. You can download our Acrobat 7 & 8 Preflight Profiles, which check for common problems.

From version 8 Acrobat is also able to apply fixes, correcting some problems by thickening lines, converting colours or removing colour profiles. Our profiles do not perform any operations that change your file, but if you go into the preflight options you can find them under "fixups" and add them.
