How to plot an color of the "Index Color" file such as the Magenta in color

[ovenegas6BFTN]

Working with a .ctb file that all the colors print in black, but I just want one color from the "Index Color" file to print in its color.  How to single handle this color that is to be printed in its color?  What needs to be done?

Thanks in advance.

Select your ctb file then press the plotter image .. now select your needed color and from Properties change it to Use object color .. see below image .

Hi,

sounds you never created/edited a ctb file, or I missunderstood you Q:

Set the color of your plotstyle* to "use object color" instead of black

!?

*plotstyle in ctb is "color nnn" 

For color 6(magenta) the plotstyle is named "color 6" and so on.

But please: Create and edit your own plotstyletables only, not a default support autodesk file.
