Digital BW, The Print

Paul,

I think I am completely and definately turned around backwards and a little 
inside out. What you are sayng is the K4+ inks are not pure carbon inks in the 
respect they are glossy compatable and potentialy mixed with other color 
pigments while the Eb4+ inks are pure carbon or at least dilutions of Eboni 
mk. So I take it the MIS K4-LK inks are glossy compatiable? Not sure why I am 
have such problems with this as it seem fairly straight forward.

I am currently using;
Eb-Mk in the K position
UT14-C in the C position
6% Eb-Mk in the M position
2% Eb-Mk in the Y position
2% UT14-C in the LC position
50% UT-M in the LM position

To be complaint with the Eb4+ specifrications I need to rearrange the inks to;

K - 100% MK
M - 18% MK
LM - 6% MK
Y - 2% MK
C - PK
LC - 30% PK

Are the only purpose of the PK/LPK inks for glossy printing & toning?

At any moment I expect to hear a loud snap when everything falls into place & 
suddenly makes sense. It will probably be a loud thud of my forehead bouncing 
off the brick wall....

Many thanks,
Phil

I'm not sure I understand what you're asking here. "K4+" 
(http://www.paulroark.com/BW-Info/4K+.pdf) used Eboni Mk for the K, but then 
used the glossy-compatible MIS carbons for the other 3 carbon core inks. Eb4+ 
uses Eboni MK and 3 dilute Eboni inks -- not glossy compatible and more neutral 
than the glossy carbon. (See http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf)

Either approach can use a variety of other inks as the "Plus" inks. In the K4+, 
to make it able to hit neutral I used LM and LC (or 50% LC). This becomes much 
like the OEM K3 when used with QTR except that I had both MK and PK in the 
printer. I used the PK as the K for glossy printing and as the most dense gray 
ink for matte printing. For my own printing, I used Epson LM then to try and 
avoid or minimize the green shift problems blended third party inks tend to 
have. 


In the Eb4+ the "default" plus inks include the MIS UT14 C (a neutral PKn) and 
UT14 LC (neutralized LK) because they are commercially available, pre-loaded in 
1400 carts and relatively inexpensive. They are fine inks, equal to what most 
dedicated neutralized B&W inksets offer. HP PK & "LK" are, currently, what I'd 
use for fine art that I'm selling if I want cooler prints. I know HP has 
balanced these to avoid the green shift. (Whether HP LC and LM [or blue] used in 
blended inks avoids the green shift is un-tested.)

Eb6-M is 18% Eboni.

> ... Eb6-Magenta ... compare with 18% MK and UT14-M?

Eb6-M = 18% Eboni, but UT14-M is K4-PK, which is glossy compatible, warmer, and 
denser than Eb6-M.

I probably would not put a variable-tone inkset in it, although the original UT1 
was a variable tone made for the 1160 and 3000 quads.

The 1100 can make a nice traditional quadtone printer, but it lacks QTR support.

I don't recommend a quadtone like the 1100 for anything except a monotone 
approach now.

(You lost me there.)
