I do magazine ad production, and many advertisers send us ad files in PDF format.
Why is it that crop lines show up on some PDF files when imported into a Quark document, but not on others?
I'm frustrated because the crop marks are in the bleed area, and I'm afraid they'll show up on the printed page.
The ads are both built to the same dimensions, and when opened in Acrobat, appear to have the crop marks in the same place.
But when I import them into Quark files, the crop marks appear in one and not the other.
Am I missing something?
Any help will be greatly appreciated.
