We have elaborate test rigs that we don't model in SW in sake of our time. Instead we have engineers take pictures and we point to items on the rig with traditional leaders in a SW drawing. The issue is that when folks print the drawing in grayscale, it doesn't seem to matter what color the leader is in SW, the leader disappears on a dark image. We are experimenting with leader color and brightness of the image etc. but wanted to know if anyone has found a fix to this issue within SW?
