1. Reveal is a plugin to show you information in various categories about the things used
in a PDF file. “Things” would be things mainly of interest in a prepress
context, but also fonts which may be of more general interest.
2. To reveal where these things are used, by showing you a live, side-byside
view of the original PDF file and the items you selected. For
instance, you could show a view using only the Helvetica font, or a
view using only the Cyan colour plate (in effect, a separation
preview)….. and so many features
