Digital BW, The Print

Well actually you will not get black with black only; there is a 
colour caste in the blacks.

Black as printed in NCA is printed in 3 parts
--the darkest by black
--mid by light black
--the highlights by CYM

all have different hues.

The grey line R=G=B is not grey and the actual grey trajectory 
twists around the grey line.

I understand it is much better with the 4000.

This makes good black really hard and makes colour not that easy 
either.

What looks like metamerism is actually slighly off colours that are 
accentuated in different light.

QTR does a really good job of black and white and does so by using 
colours with the blacks if you read the profile documentation 
carefully.

Or in other words the sloppyness goes far beyond what you imagine.

If you want to see more, internet search on "color warbles" to find 
for an interesting article by Bill Atkinson.
