Digital BW, The Print

I have struggled to get a R220 to work as well with MISPRO color inks 
as it has with MIS UTR2 inks.

Profiles from inkjetart.com, Cathy's profiles and PrintFixPro have 
all come out with some serious problems as the ICC profiling process 
doesn't seem adequate to correct huge the color shifts when using 
these pigment inks with a driver that expects very different dye-
based inks.

I was intrigued by this method of using adjustment layers instead of 
ICCs and was wondering if Paul or anybody could offer advice for how 
to derive my own curves for use with the R220.

I have a PrintFixPro unit.

I also bought an R1800 hoping that would solve my color issues but 
the model I got seems to spray ink internally, so I have to have it 
replaced. In the meantime, back to the R220.

Best,
Roger
