PDF Export - Larger Images missing right border Edited

[AccountName:NBzD]

Hi, 

I have multiple images within a PDF Export. Smaller images have no issues but larger images do. Due to the nature of the task at hand, larger images have to displayed e.g. 600 to 900px size.

However, the larger images are all missing their right-border in the PDF export. I understand this could be a PDF Stylesheet setting but I can't seem to find the appropriate one. 

Any ideas? 

Thanks in advance for your help.
