Which color inks did you have in the 1800?

I have not had any clogging issues, but, nonetheless, I've set mine 
up now with Eboni in C, MK and PK, and cleaning fluid "insulatore" 
next to the 3 Eboni positions.  

Because I do want to continue to experiment with the glossy papers 
and 100% carbon printing, I also have MIS Pro PK in the Y position 
and glop in the GO and Blue spots.  This leaves one space on each 
side of the Eboni spots for cleaning fluid.  I think there may be 
some value in separating the high load MK from the glossy ink and 
glop, which obviously have a fair amount of binder in them. 

The GO position is just like a color position with respect to 
cleaning.  For nozzle checks, the checkerboard pattern seems to 
indicate how it is performing, though I am clueless as to how it does 
so.
