When you are satisfied with your design click on [Export to PDF] to export your design as a print-ready PDF.
To easily identify the export files the suggested name for the PDF file contains the Effect type + the Opacity.
The fact that you have ticked one or both check boxes ([Mirror back image] and [Image area mask] ) is not part of the suggested name when you export your PDF file. However, this information is helpful if you want to nest jobs (i.e. using ProCut Prepress) before you open the PDF files in the Arizona Xpert Engine. In that case it is advised to add this information to the PDF name, e.g. adobe_recipes_all_v2_Blockout_Low-image-area-mask, to make sure that you don't mix different recipes.
To make sure your exported print-ready PDF contains the image area mask, check that the Live Paint Bucket is not selected in the Adobe Illustrator Tools Panel before exporting.
