My stroke is bleeding, and I was wondering how to clean up dirty stroke corners.

I'm creating a simple envelope for a newsletter (rectangle and triangle), but the triangle stroke is bleeding over. Aligning the stroke to the inside or outside doesn't allow me to match the corners how I want.

What is the best way to resolve this issue?

The image on the left is a triangle over a rectangle, and the right is a rectangle and two lines that don't match.

  • One way to approach this is to expand the triangle and rectangle and then use Pathfinder divide to help delete the miter points that are sticking out at the top. I explained this process in a recent answer.

Try to set a lower value for the Corner Limit. This cuts long tails in the case of acute corners. Experiment with it because the threshold value depends on the angle.
