If you want to export as an interactive PDF, you can always increase the page size and add the crop marks manually.
This may help when creating crop marks?...
If you want crop marks on all your pdf’s…
Indesign - File Document Set Up
Click on Bleed Settings e.g. 3mm or your choice (Top, Bottom, Inside, Outside) click OK.
Keep Indesign page open, then go to:
File - Adobe PDF Presets
Click for example ‘Press Quality’ - Save
Dialogue box appears
Click on ‘Marks and Bleeds’ then click on Marks and check ‘Crop Marks’
Click on ‘Bleeds and Slug’
Check ‘Use Document Bleed Settings' eg 3mm - Export.
Your pdf’s will then have crop marks, governed by the distance of your ‘Bleed Settings’ e.g. 3mm.
SInce the introduction of Interactive PDF as a separate option, any PDF (Print) preset is useless if you want interactive content as the OP does, and the Interactive dilaog has no provision for crops. And crop marks are governed by the offset value, not the bleed setting. In your screen shot above your crop marks will encroach almost a mm into the bleed area you've set. It's important to reset the offset value from the default to at least as much as the bleed allowance.
Hello Peter, the screen shot may be a little misleading, I was just trying to show what the dialgue box looked like and where the appropriate bleed settings were, sorry for any confusion.
