Black lines around shapes after exported as interactive PDF

[SophiaPP]

Hi,

After I export my indesign file into interactive pdf, some of the shapes/text boxes have thin black lines around them. Both of their fill and stroke are nothing. 

I combed through this community and saw several solutions such as uncheck the "smooth lineart" and "Smooth images" on Acrobat. I did uncheck both fields, but there is nothing changed.

I can't export to PDF/x-4 as other suggested as well, because it would eleminate all the interactive buttons in my file.

Please help! Thanks!

Hi Sophia,

could be the PDF Appearance of a hyperlink.

You can set it to "Invisible Rectangle" like in the screenshot below:

Thank you very much, @Laubender! This is exactly what had happened!

Acrobat may be automatically detecting form fields. Go to Tools> Prepare Forms in Acrobat, do the frames appear as form fields? You can select and delete them. In Acrobat, go to Preferences> Forms> Automatically detect form fields (uncheck).

I've never heard of Acrobat doing something like that. Only URLs are auto-detected.
