Digital BW, The Print

Paul,

You are a tremendous help and a very patient person. Thank you for both. I think 
I lack the basic understanding of what each inkset is developed from and 
purposed for. The rest is a confusion over the the naming of the different 
inks.For example, "Note that UT14 LM is LK, which is 30% of UT14-M, which is 
simply MIS K4-PK". 


According to InkSuppy's website, the MIS K4 inks are Epson K3 compatable 
replacments and are matte + glossy. Eboni is a pure carbon core matte but more 
neutral and stable than the K4 inks. For glossy B&W prints I would elect the K4 
inks using LC & LM for toning = K4+. If I wanted more stability with the ability 
to print glossy, I would select the Eb4+ inset wth UT14-C & UT14-LC for printing 
glossy. Correct?

Yes- I meant to type "I am using 30% UT14-M in the LM position". However, if the 
K4-PK is the same as 30% UT14-M, what makes the K4-PK different from the K4-LK 
or LLK if the LK & LLK are glossy compatiable as well? Are these just diffrent 
dilitions of K4-K? Please correct me if I am mistaken but doesnt PK identify 
Photo Black meaning it is glossy compatiable versus MK which is Matte Black? 
Please believe me when I say I am honestly trying to understand this and not 
being argumentative or sarcastic. To the uninformed, it apears more logical to 
have a natural progressin of K4-K, K4-LK, K4-LLK, and finally K4-LLLK especially 
if the inks orginate from the K4-K ink. By injecting a K4-PK leads me to think 
there is a difference and naturally assume the K4-LK & LLK are non-glossy inks 
and the same as the Eb6-K inks.

Is there any difference between the MIS stock base (ESC-Base-UC), glop, and 
generic base? How does this difference if any affect final print tone? Impact on 
the printer?? I have been using the MIS clear stock UC compatiable base to mix 
the different dilitions. Is this a bad thing? I know there is a most cost 
effective apporach but a 4ounce bottle has lasted several months.

My intent is to achieve the most neutral inkset with the longest life stability. 
For glossy prints I use the R2400 with Exibition Fiber or Ilford Smooth Pearl. 
This seems to work fine for the time. Reading through the 1400-Eboni6 document, 
I see the ink denisty is pretty standard: K,C,M,LC,LM, & finally that poor 
little Yellow. Would I be wrong in assuming the densities should be 100%, 30%, 
18%, 9%, 6%, and 2% respectively? This would relay solely on paper choice to 
determine the actual print tone of warmth vs neutral though. How well would it 
fair using UT14LC as a toner to help control the Lab b warmth in the mid 
tones? This would be moving back towards the Eb4+ with the C & LC inks, yes?

So far, as the cloud of confusion begins to disipate, I see need to look closer 
at Eboni-6 than the K4+ or Eb4+. I think I have more adventure ahead of me but 
with your help I know that I will arrive at the look & tone that I 
envision. Many thanks. I am beginning to think I just need to pull the plug, 
step back, think about it, and re-set the inks using a fresh perspective.

Phil

The glossy carbons from MIS -- for example the K4 PK, LK, & LLK are pure carbon 
-- no colors mixed in. The "Plus" inks are where the color is.

The reasons I came up with the Eboni-6 and 4 as opposed to use the MIS K4 PK, LK 
& LLK is that the Eboni carbons are more neutral and have almost no binder in 
them, being matte paper only. Glossy pigs are where the binder is needed to 
stick them onto the slick paper ... and other things.

That is a very light neutral-cool ink.

Is that 50% UT14-M? Note that UT14 LM is LK, which is 30% of UT14-M, which is 
simply MIS K4-PK.

And if you're mixing these as opposed to buying MIS Eb6-M, LM, and Y, use the 
generic base and not glop.

> C - PK
> LC - 30% PK

Yes, that is one set that can go there. The defaults are UT14 C and LC -- 
neutralized PK and LK. The idea is that many want a more neutral ink and some 
minimal glossy capability. The 100% carbon PK and LK give you a sepia tone on 
glossy paper.

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

Yes. If you want 100% carbon on matte and the tones that can achieve, then I'd 
recommend Eboni-6, not the Eboni-4 Plus the 2 others.

For the full Eboni-6, see http://www.paulroark.com/BW-Info/Eboni-6.pdf 

Hope this helps.
