deep dark shadows monochromatic gum

hi all,

What is the deepest value that can be achived from a typical (not too dark or
light) pigment ? i'm trying now to make monochromatic gum bichormate (in
violet) but the most important part of those prints are the shadows - i want
them in deep , almost black value - those prints im mading in violet.

Is it the good idea to mix violet with black pigment to last , most dark
layer?

-some useful tips quickly needed :)

regrds,
paul gega.
