Digital BW, The Print

I have been experimenting with different B&W tones using the ABW driver.
When I set the tone to Warm and Light, I have noticed that no yellow seems
to be used, at least, after many prints my yellow cartridge is still showing
full. When I set the tone to Neutral and then adjust Horizontal and
Vertical each to -15, I see yellow being used. What's up here ? Has anyone
else noticed the same phenomenon ?

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

Clayton,

As I understand it from something I read somewhere (can never keep track of
these things) when you select "warm" as your tone in ABW you are really
using the three blacks which are carbon-based, ergo the warm tone, which is
not sepia, and thus does not require the other colors required to make
sepia.

Brian, you must have read that about QTR, where it is indeed the case.
But any setting in ABW uses a fair amount of color ink.
