I created a new business card, saved it as a CC file, then exported the file as a PDF. Upon placing that file in another document to print 12 up, the pdf size was about 1.9 inches wide by 3'' tall.
Why does it not export the file as the exact dimension?
This is so frustrating!
It should be exact. If you export with bleeds the bleeds would be included. If you direct select (white arrow tool) is the placed PDF at 100%. Also you don't have to export to PDF, you can directly place the b-card ID file in to another ID file.
It will also depend on your selected crop options during import and what is on the page. Show the import options and for crop choose Media to get the full-size PDF. Choosing Art or Bounding Box is going to import only part of the page if the edges are blank.
