Digital BW, The Print

Paul,

I've started a project designing a UT2-like inkset for the 
R1800/R1900.  The UT2 inkset you designed for the 1280 was fun to use 
and I miss its flexibility.  I've read through all the applicable 
white papers on your website and have some questions.  Thanks in 
advance for your help and all you contribute to this forum.

For now, I'm switching color and BW inks back and forth in the same 
printer.  Each inkset stays in the printer for at least a month or 
more and I may go to a dedicated printer in the future as budget 
allows.  I use MIS or IS for all inks, there are no OEM used inks in 
the printer.  I'm using QTR and have cut-and-pasted from the 3MK 
profiles you generated as the starting point.  I have also found a 
source of totally spongeless carts, so EB-6 inks are an option.

My configuration at this time (subject to change) is 3-MK, 2-PK, GO, 
R1800 blue (which is really purple), and a sepia slot.  I started 
with the R1800 red as the sepia ink as you suggested, but it wasn't 
what I was looking for.  After making color samples of all the inks I 
have, the UT2 sepia (yellow position) was the closest ink to what I 
want.  This is based on comparing the color samples to some old (late 
1800's and early 1900's) family photos.  However wanting the most fad 
resistant inks, I thought there may be a better way to make that 
ink.  I was thinking of mixing some MK, R1800 yellow and maybe some 
R1800 magenta.  Would these be good choices from a permanence 
viewpoint?  Is there a ratio you'd recommend as a starting point to 
match the UT2 sepia?  Also, would MIS UC-base be good for dilution?  
If not, what would you recommend?

I am going to look into a LK position as well.  How does one part MK 
to four parts base sound?  In the future, I will probably also try 
R1800 cyan in place of the blue (purple).

I know I'm covering a lot of ground here, so thanks for your patience 
with this student of yours!
