PDF maken via Indesign lukt niet

Try exporting half the amount of pages - if it's 100 pages - try 1-50 then try 51-100

Whatever side it crashes on is where the problem lies. If it say crashes on 1-50 then try 1-25 then 26-50 

Keep narrowing down the pages.

If you have only 1 page you could try deleting elements 1 by 1 to see what is causing it.

Other methods

If a document is not behaving well then try 

File>Export 

Choose IDML

Open the IDML in InDesign
Save the file as a new InDesign file with a new name
See if the issue persists.
