White lines when printing to PDF after flattening

[elodie15B9]

Hi, White lines appear on my PDF and some also on paper after flattening transparency and printing to Adobe PDF. This is a new problem for me. I tried a bunch of tricks but not solved. Using CS6.

Thanks for your help.

elodie,

Maybe a silly question, but what happens if you Save a Copy or print to Adobe PDF?

Same yes

Hi. Usually, that happens when you export flattening the transparency. You can try exporting using a preset that doesn't apply flattening.
