Fine lines appear after importing in InDesign and export as Print PDF

Hello all,
Maybe someone can help me, I am a bit desperate. ;((

I have created a graphic in Fresco, which I want to use in InDesign for a flyer.

When I create a preview PDF from InDesign for my client (just for viewing on the computer), everything is rendered great.

But as soon as I create a PDF according to the desired specifications of the printshop (standards: PDF/X-1a 2001 and profile: ISO Coated v2 300% (ECI)) I suddenly get fine white lines below the graphics.
I have already tried everything, saved different formats: SVP, PNG, and also directly placed the Illustrator file. Always these unwanted lines appear!

I have also sent from Fresco to Illustrator and re-exported from there as PNG or SVG, same problem - although the lines are not visible in Fresco or Illustrator itself at all!!!

The funny thing is that I have already used another graphic from Fresco where this does not happen: No lines, no artifacts at all.

What am I doing wrong, how can I save a clean file that I can use for printing? Is there a recommended workflow for export that works well for print?

P.S. in my opinion it is obviously Fresco after all or could it be an InDesign problem?

Thank you very much for your help ;))

Hello everybody,

I've got some help in a FB-Group. ;o) Obviously this is an old problem with Adobe Acrobat combined with  the PDF-X/3:2002 standard often required by printers in which transparencies are prohibited. Here is an article in German with the description:

Solution is: You can turn off anti-aliasing in the Acrobat preferences. Under Acrobat > Preferences > Page Display you can simply uncheck "smooth line art". This makes the edges of vector data a bit more pixelated, but the white lines of anti-aliasing disappear immediately.

 

I tried and it works! Maybe this can be useful for people with the same problem :))

Have a good day!
