Extensis has released a free Suitcase plug-in for Adobe InDesign 2.0 that automatically activates fonts used by the application.

It's available free for registered users of Suitcase 10 for OS X.

“InDesign has proven to be a leading design and publishing solution for creative professionals,” said Michael Wong, Suitcase product manager.

“By incorporating Apple’s FontSync technology into this plug-in, Extensis equips InDesign users with a font-management solution that ensures the correct font will be automatically activated every time," he explained.

FontSync is an Apple developed font-matching technology that's been built into every version of its operating systems since Mac OS 9.

It identifies fonts based on the content of the font, such as whether or not the font is Postscript or TrueType, what the kerning has been set to, and which ligatures it includes.
