In message 88451 you advised me "For a neutral PK print, take a look
at the UT-RC inkset. The PKN is quite nice.
It has some cyan and R800 Blue in it, but I held it down as much as I
could and still have what I considered a good black black only print."

Following this advice I bought 24 Oz of "UTPKN-4", installed them in a
new continuous supply system and used loads of expensive new fiber
papers in testing.

Is this the wrong ink to have used?  

You also said "There are also dilute RC inks for the R260 etc. that
would make a good inkset for the 1800, but I have not gone there." for
this reason I did not buy them. 

Possibly this accounts for the poor results I had from QTR
linearization but I now have photoshop curves to linearize these.

Please supply the link to what I should buy when I have used up all
this stuff.  Perhaps I should just ditch it.
