Coloured hatches plotting grey

[xavierd24]

Hi all. I'm fairly new to AutoCAD so this may be a simple fix.

I'm trying to plot (DWG to PDF) a drawing that has a solid colour hatch however the hatch appears grey in the PDF. I'm using monochrome.ctb and the coloured hatch is a True Colour so I thought it would print. Have I missed something something here?

Please let me know if you need anymore information. Thank!

Using monochrome changes everything to black and white. Use NONE and change the colours of the other objects to black/white (Number 7) on the colour palette

Thanks for your reply. This would make all object in model space display as black right? I need them to keep their assigned colour in model space to make the document easy to work with. Is there another work around for this?
TIA

At the command line type STYLESMANAGER. Now choose. ADD A PLOT STYLE TABLE WIZARD. 

You can then create your own style and set it to plot certain colours as black and the rest as normal.

Is there a reason changing colour codes to (use objects colour) in monochrome.ctb plotstyle doesn't make those colours plot in that colour? They display correctly in Layout but always plot black. Is there a way to override this rather than making a whole new plot style? Thanks

It is good practice NOT TO CHANGE the default AutoCAD style tables.

As somebody else might want to use the default style and suddenly find it's not plotting as it should.

Forgive me for asking, this is just a question, nothing more, is there a language barrier here my friend?
MONOCHROME means NO COLOR.
If you want COLOR, using the ACADLT.CTB plot style driver, or if you are for-whatever-reason forced to use MONOCRHOME by your overlords otherwise you will face punishment for it, then those colors have to be TRUECOLORS as explained here https://autocadtips1.com/2011/12/07/plot-color-regardless-of-ctb-or-stb-file/
