color setting in print phase

[Tantocattivo]

Hello everyone,
use autocad 2021 and I am having difficulty printing in black and white or gray scale. practically a block has a pantone color and not a classic autocad, so when I go to print I can not tell to autocad this pantone print it black or yellow or more or less often.

normally setting a monochromatic .ctb file in the printing styles table (ex. monochrome.ctb) print takes place in black and white. then assigning the line thicknesses suitable to the various colors during printing the lines will have different thickness.

 

[Tristan]

only index colors are read by .ctb
color change and use one of the 255 colors index

 

[Cristallo]

true color colors and pantone colors are printed of the assigned color, does not center anything the ctb.
you can only change its thickness through the single entity linewight or layer if you want to do so for groups.
as tristan says only the 255 standard coluri are read by the ctb
