How do I remove blurry lines in 2D view

I’m experiencing an issue in Rhino 8 where some lines in my 2D technical drawings appear fuzzy or unclear when exported or printed as PDF. The issue occurs even when there are no duplicate or overlapping lines underneath. I never experienced this in Rhino 5.

Hi Anne,

Can you run the SystemInfo command in Rhino and post the results? We may also need an example file and a screenshot of your print settings as well. Thanks!
