6 white lines on the side of exported PDF file

[Marek Ševčík]

Hello, what are these white lines? They appear on the side of an exported PDF file from Illustrator.

1 of them is intentional, the other five aren't.

I tried removing it. Didn't help.

I have all print marks unchecked when exporting.

Thanks for any ideas!

Which version of Illustrator are you using?

Also, can you share the original Illustrator file (.ai) as well as the exported PDF file?

I'm using llustrator v 25.0

I can share the files. Where should i send them?

I would prefer not to share it with everyone.

In case it is strictly confidential, you may upload it to any file sharing provider and send me a private message with the download link.

Or you may, of course, simplify your file, such that it only shows the issue, but not the confidential parts of it, and then provide a public download link, so all participants may have a look.
