I'm trying to figure out which PK to use in the R1800.

Paul shared some advice here:
http://www.paulroark.com/BW-Info/3MK-Glossy.pdf

"Initially I used MIS K4-PK is in the Red position, and MIS R2 PK is 
in the Blue position.  I will probably change this, as the MP-PK 
seems to achieve a higher dmax at a lower ink limit than the 4k-PK. 
The R2-PK was optimized for the R200 printer and has 10% blue 
pigments in it.
I'm having a little trouble deciphering which PK is which.  
MP PK = ?  4k-PK= K4-PK?

I'm wondering what Paul and others settled on for a high Dmax on 
gloss-type papers with this printer. 

I have UTR2 PK and MISPRO PK lying around that I used with my R220.  
I'm finding that the PK I got from the MIS R1800 color ink set is 
hiting max density too soon and forcing me to drop back from Photo 
RPM to best photo to avoid density reversals.  Unfortunately doing so 
leaves me with a lower Dmax than I was getting with the R220 and some 
moderate microbanding.

In my latest experiments with PK in an 1800, I got better results 
with MIS MP-PK.  "MP" = MISPRO Achival color pigments. 
 
See http://www.inksupply.com/arcink_mispro.cfm  

Carl may have learned more since I stopped my glossy paper 
experiments.

The MISPRO PK is the one I found worked best.

Sorry if this question is obvious or already have been raised. I still have
some difficulties in understanding some aspects of colour management. F.ex.
I don't have enough knowledge to fully understand whether it  is possible to
make ICC profiles that allow accurate softproofing in Photoshop CS3 when
printing through the QTR rip on an Epson R1800 using Pauls 3K setup. I have
printfix pro from colourvision, so I can produce measurement-based ICC
profiles at will.

Would really appreciate to have this clarified.

 

Thanks,

Peter

It is possible and advisable. But the profiler that comes with QTR would be the way to go. 
Apparently it's easy to learn how to use the device that came with printfix pro with Create 
ICC PRofile. Others here would know that. 
Just last week I made a "Create ICC PRofile" profile for someone who uses QTR, and again 
it helped them.
You have all the tools, give it a try.

Peter,

As Tyler noted, the QTR ICCs do allow soft proofing.  If just the Lab 
L data is put into the ICC and you use View>Proof Setup>Custom and 
load the ICC, you'll see the relative densities.  If the Lab A and B 
data were also put into the ICC, you'll also see the tones.

When you embed the data in Create ICC,  just have the tops of the 
columns labeled L, A, and B -- with tabs between them like the data 
itself.

Roy's pre-made gray matte ICC can also be used for soft proofing at 
least the relative densities.  I have those (matte and glossy) set up 
as PS actions and on function keys.  Since I mostly work in the 
relatively neutral range, I found the relative density match is all I 
need, and the function key/PS action approach is fast and works very 
well.

(Note that I often have or use other methods of matching the monitor 
to the print because Elements users do not have the softproofing 
tools that are in full Photoshop.)
