Plotting with all black - Grey not showing!!

Hey guys, I'm having a little problem here.

So, in the "Plot style table editor" I set all colours to show black. Except, the colour 254 which is grey, I set it to show as 254.

Problem here is, when I print, my solid hatches which are in grey, do not show. What can I do?

Hope I made myself clear

Any help would be appreciated

Thank you

try "Use Object Color" instead.

If not, set it to Black, turn Dither to ON, and set the screening to say.... 50% or so. This is actually a much better option in my opinion.
