Marek,
If I understand your note below, then you have too much ink/density for both
processes.
Actually Black Ink Only will give you more density. Currently for gum, by
moving the right endpoint of the curve down from 100% to 60%, you are compressing
your tones so that you lose about 40% of them. Black Ink Only will probably
cause that loss to increase.
