I am creating a PDF for printing, and I got some weird artifacts on places where elements with the same color overlap. My workflow is from Illustrator to InDesign to PDF, and to be honest I dont know where the problem comes from.
Here is a screenshot of what I mean :
Here is another one where you can see that they are really overlapping The lower beige part is on top of the upper one, whose green outlines you can see
The weird thing is, it depends on the actual Zoom level whether or not you see the line. How can I get rid of this? I am scared this will be visible on the print later on...
INSERT: These screenshots are from Illustrator CC2017.1.0 on Mac. The problem is visible also in InDesign, Acrobat and Adobe reader. The problematic shapes are only simple paths - one triangle and one half circle.
