Illustrator Alignement Problem
Hello, i have a problem when i need to vectorise precisely on Illustrator, i can try every parameter, the most precise i can get is that :

I tough it's a pixel or grid alignement problem, but i check/uncheck all alignement option i can found on Illustrator, it's every time the same problem when i want precision. I try also to double/triple DPI on photoshop before import (600 / 1200dpi), but it don't change anything.
How can i desactivate all pixel/grid alignement ??
I can after vectorisation, move every vectorised line where i want, but i have some time more than 1000 square / round to vectorise precisely in order to make a cut with cue. Please help me ![]()
Julien.
