Reply To: Flattening transparencies with a spot color

I did not have Overprint Preview turned on (I do now — thanks!). I was still running into problems with PDF/X4. Our technical rep at the printer had me export the logo file as a PDF/x1a (SWOP 2 destination); when I place that PDF on the cover file and export with the printer’s job options, the separations are correct. I can’t explain why it works, but it does. (Phew!) Thanks so much for your help!
