We use Trade Gothic Lt. Std. No. 18 and No. 20 (condensed and bold) as well as Gotham (book, bold, medium) fonts. Our outside creative teams have these fonts as well as use them when working on brochures and such for us. However, whenever we receive the packaged design file and work on it at another time Adobe (typically InDesign) always prompts us to relink the fonts otherwise it will default to Minion Pro. Any idea why this is happening? It is rather annoying. Though it is fairly simple to do, there have been times when there have been several things we need to review in order to determine which font it should be, exactly.
Moving this discussion to the InDesign forum.
It sounds like a font version mismatch between users.
