After importing an eps logo into Indesign CS5 it previews fine when Overprint Preview is turned off, but when overprint view is turned on only the logo icon appears, the font disappears.
The font has been outlined - the logo is solid white and appearing on a solid black background. When exporting the file to pdf the font also disappears. I have tried saving the file as an AI file with the same result.
First of all you should be using native Illustrator .ai files with PDF compatibility turned on (this shows up in the options dialogue after you save).
Your logo was converted from artwork originally done in black with the Overprint Fill attribute turned on. Overprint tells the output device not to know out the colour below the logo. When printing black, this makes sense. When printing white, this effectively makes the logo vanish, since the only way to print white is by knocking out.
Open the logo in Illustrator and select all the vanishing white artwork (probably a Select All will do). Open the Attributes panel and turn off Overprint Fill. Save as an Illustrator file and place that.
Thanks for taking the time to answer, this did the trick! I have only ever had this happen once before and never knew why.
