I'm helping a friend with a PDF export issue. She created a banner that is 120" wide in InDesign CS6. There is a PS image in the background with outlined text on top of it. The text has a drop shadow applied.
When exported to PDF, the drop shadow disappears. We've tried exporting with a variety of Acrobat settings. The Flattening setting is at Medium. The drop shadow works fine at a smaller document size in CS6.
The same file in CS4 exports with no problem at 120" in width.
