weird Outlines around pictures in PDF

[Lexis]

 

when i create PDF´s there are thin black lines around all single elements. I tried to reduce everything to one layer before saving, but that doesn't seem to solve the problem.

Any idea what I can do?

Best regards

Hi @Lexis ,

Welcome to the forums. 

Can you please attach the .afdesign or .afphoto file? 

Thanks,

Gabe.
