how to change thickness of the staff lines
Hello, I am new to this forum, and I apologize if this was answered before but I cannot find a way to change the thickness of the staff lines. My problem is that when I export the score to pdf, the staff will kind of look poorly when printed (some lines are faded, others are thicker) and I want to somehow make the lines thicker, assuming that this will improve the pdf look. Or, if there is another way, please let me know.
Thank you and I really appreciate your help,
