The UT7 inks are physically compatible with the 1800.  If you're 
proficient with QTR you could certainly come up with some combination 
that would make the 1800 a variable tone printer.

The UT7 was made so that it could run on a k2 printer using the Epson 
driver.  That won't work with the 1800.  The LK, in particular, is 
going to be redundant and not needed.  It was a compromise due to the 
Epson driver and the inability to stop the LK from being used.  It is 
a blended ink -- just a little blue in it.


> I would like to use light black, dark gray, light gray,

As noted above, I'd avoid the UT7 LK. It simply will not add much.  
The UT7 light and dark grays -- in addition to an MK or PK -- should 
be all you'll need for your carbon channel.  Use broad skirts -- lots 
of overlap -- on the curves to suppress microbanding.

If you dump the LK, you could ad a PK and have glossy compatibility.

Good luck with the system.
