Digital BW, The Print

Hello everybody

I somehow managed to get fairly good black and white prints in 
the "colour position" of the driver using the curve editor of the GB 
software. But only for artificial lighting. In daylight conditions
the 
prints look greenish. 

However, before returning to classical Quadtone Printing with my 1160 
I should like to find out whether "black only printing" at 2880dpi 
using matte black ink and EAM is possible at all. I read Clayton 
Jones' "three articles" (actually now four articles) and am beginning 
to understand the interaction of the two "black boxes", i.e. PS7 and 
the EPSON 2100 driver.

But when I use "black" in the driver of the 2100 the output is
strange 
to say the least (much too light). No problem with the black position 
in the 870 and the 1160, though. 

Question 1: Has anyone tried the "transfer function" for BO 
printing and could they please provide the 13 figures necessary to
get 
a smooth curve. I tried myself, but to no avail.

Question 2: Any other approach to good BO printing with the 2100.

Question 3: Will it ever become possible to use matte black ink plus 
light grey ink for metamerism-free black and white printing?  

Thanks

Mathias
