Digital BW, The Print

I haven't posted a message in a long while, several months, but I've 
been wanting to post my findings as to various degrees of warm vs. 
neutral prints by mixing the warm and neutral cartridges (carts) on 
my Epson C84.  Maybe someone has already posted this info but I 
haven't seen it and maybe this will be helpful to others using the 
EZ B&W inks, which are absolutely great.  The C84 & C86 are only 
fair when printing color as compared to Epsons photo grade printers, 
but are wonderful for B&W with the EZ ink sets.

Before giving you the particulars below here is my results rating 
from neutral to the warmest prints.
CW = Cyan warm cart; MN = Magenta neutral cart and so on...  There 
are only 8 different combinations of the warm and neutral carts.

1. CN-MN-YN  the most neutral print
2. CN-MN-YW  a little warmer
3. CW-MN-YN
4. CN-MW-YN
5. CW-MN-YW
6. CW-MW-YN
7. CN-MW-YW
8. CW-MW-YW  obviously the warmest

I found very little difference between combinations 3&4, and also 
between 6&7 and with further testing might flip-flop.  There was a 
more decernable difference between the other steps.

This is how I performed the test and other useful info:  I have the 
neutral set of carts (cartridges) and a warm set of carts.  Both 
sets are used with the Eboni black since the shades between warm and 
neutral is determined in the midtones and highlights.  One thing 
everyone should know if you don't already is that the ink in the 
cyan (C), magenta (M), and the yellow (Y) in both the warm carts and 
the neutral carts is exactly the same ink.  In other words when 
refilling the warm and neutral carts all you need is one bottle of 
the warm and one bottle of the neutral for each of the C,M, and Y 
carts.  I comfirmed this with MIS and Paul Roark.  I used a Epson 
C84 printer with Epson Heavyweight Matte Paper, which has optical 
brightners (OB).  I find that in general papers with OB's print 
colder or more neutral and those without OB's tend to print warmer.
The rating from the most neutral to warmest was by sight and 
therefore somewhat subjective, but isn't that the way it is with 
everything about B&W prints.

Hope this is helpful,
Randy
