That's good advice. The z3100/3200 PK carts are not cheap, but when
diluted the costs of the overall inkset are very reasonable.
With the MIS gloss optimizer they are a bit warmer than the HP grays or the
PK diluted with the generic base I use, but HP pigments bronze badly
without a gloss optimizer. I have never used the OCP optimizer.
If the prints are too cool for you, adding an MIS glossy carbon to the
printer can warm things up nicely.

Be sure there are third party empty carts available from a reputable
company. They may tell you what the capacity of the carts is.
I often find it easier to mix the inks in quantities that are large enough
to fill small bottles. In the US the MIS 4 oz./110 ml wide top bottles are
very convenient. It makes re-filling and mixing lighter inks sequentially
easier.
Do you have a scales, or are going to use syringes? If syringes, stay with
simple mixing ratios like 1:2, 1:3, etc. Mixing the lighter ink from the
next darker may make for better accuracy with syringes. Using full 10 cc
syringes as counting units simplifies and keeps the errors down.

The dilution formula or ratio going from dense to lighter that is very
common and I use with scales is 30% dense ink and 70% dilution base. For
easier syringe mixing, I recommend a 33.3% or 1:2 mixing for ease. HP is
close to this, as I recall. As long as you are consistent, the exact
percentage is not that important. This is the ratio you can use to go down
different progressions of ink densities that will make up a partitioned
channel (what I can a channel, anyway).
If you have all HP dilutions in the printer and no toners (including one or
two warm carbon inks) you'll have more than enough inks. Maybe for
simplicity and to be sure you'll be happy with the HP tone you ought to
start with a K and 5 grays. You might want to just put your clear base in
2 spots to hold them for now.
PK,
33.3% PK (1:2),
20% PK (1:4 mix),
11.1% PK (1:2 mix of the 33.3%),
6.67% PK (1:2 mix of the 20%)
3.7% PK (1:2 mix of the 11%)
The first 5 of the above is what I used for the Noritsu NK5 inkset <
http://www.paulroark.com/BW-Info/4000-Noritsu-5K-Plus.pdf>. The partition
of those inks looks as follows:
http://www.paulroark.com/BW-Info/NK5-Partition.pdf
There is room to add another light ink -- like the 3.7% suggested above.
While this prints fine, you may later want to change it into a
multi-channel or multi-profile set so you get more overlaps.
I just suggest this as a rather generic approach. It usually works well.
With QTR, the inks can be put anywhere. To keep the Epson drive option
open, I'd have these in the following positions:
PK = K
33.3% = C
20% = M
11.1% = LC
6.67% = LM
3.7% PK = Y.
(However, the Epson driver will not work with clear ink in the LLK-LK
spots. This is just a starting place.)
Good luck.
