Digital BW, The Print

Hello Brian,

I'm not sure about the yellow, but I think that when you select one of
the preset tones, such as Warm, that all it's doing is moving the tone
controls to preset values.  Try selecting each tone from the list, and
after each one see what the values are.

One experiment that would be quick and easy is print a step wedge
using "Warm", then print another by manually setting the controls to
the same values.  If a different set of inks is used they should be
different.

Clayton
