How to get "grays" in a monochrome print

[vikiw_bend]

I could use some help on this. I use a light gray for entities that are for reference. An example on a current plan is showing the plumbing fixtures on the wall and floor framing plans, or showing skylights "above" on plans other than the roof framing plan. However, when I turn off the colors in the drawing file, or when I send it to layout, everything becomes uniformly black. What do I need to do so that in a monochrome print, entities that are supposed to be "background" will show up as a light gray? I'm using X6. Appreciate the help.

Print to .pdf in color, print to paper from .pdf, in b&w.

Also set "Color off" to grayscale in preferences

Thanks, I could not find how to set the Chief PDF to Greyscale - did not think of prefences - Bump for other less informed as myself.

I use layer sets to put everything in black/white/grey...and then print in color.

Thanks, Joey, that sounds worth setting up.

Perry's post #3 I believe is the correct answer. I just wish he had told me about this 7 years ago.
