I have a project in InDesign and whether I print directly from InDesign or export and print from PDF the thin white lines appear.
I have attempted all the solutions from this page Thin white, dark lines (stitching) | Export to PDF | InDesign CS2 and later,
but haven't had any luck.
One layer are colored circles with affects and the top layer is text.
Thanks in advance!
What export settings are you using? In my experience, letting Acrobat do the flattening is more reliable than if ID does it, but there's no guarantee that you won't see stitching on any particular printer unless you eliminate transparency from the design.
