I'm also having huge problems overprinting several process colors.
It's a straight CMYK book with no spot colors, so i'm using multiple overprints to add color depth (within 270%).
But, InDesign seems to have lost the additive values and knocks out each plate beneath with the overprinting values...? I've tried various things but can't achieve accurate over prints without disturbing the color beneath!
I need help on a workaround as I have a deadline in 5 hours!
