Digital BW, The Print

>When you say something is 14 units warm what measurement scale

I use the difference between the cyan and yellow spectrophotometer readings
as a simplified measure of relative warmth or coolness.  If, for example, Y
is 0.60 and C is 0.55, I'd call the print warm by 5 units.  This would be a
typical medium warm, midtone reading.  

The neutral I aim for is a 50% reading of C = 0.61, M = 0.62, Y = 0,61.
Since C = Y, it would be "neutral."  The magenta being one unit (one
one-hundredth [0.01] actually) above C & Y is what gives the "selenium"
look.

Since I the variable-tone inksets, in effect, pull the print along a
one-dimensional axis, the one unit relative measure (difference between cyan
and yellow) acts as a good, simplified way to compare tones or hues.

I hope this helps clarify my short hand.
