Reply To: Problems Exporting Placed PSD with Transparent Background

<<Exporting the file to a PDF/X-1a file does work, so technically I have a solution. But doesn?t it seem strange that it would work in an older standard and not the newer one?>>

No, not really. PDF/x1a is basically a “lowest common denominator” format. Your image is being flattened, so the fact that Preview will display the image is no surprise.

Yes, sooner or later someone will try to open the X4 on a Mac using Preview, but since Reader is free, I’d just point them toward the Adobe site and be done with it.
