Hi Babolat75,
I have seen it a few times. In one case, we changed one of the four process aniloxes from 60-degree to 30-degree to solve it. In another case, I looked at the screens and confirmed that they were all made at 0-degrees. Fixing that solved the moiré.
Sometimes the designs seems to fails, even with the usual angles. Perhaps playing with the angles for this particular design will help. I would Google "screen angles for flexo", and similar terms, to see what folks are doing. Also, I would search this forum for screen angles.
