QTR-Quadtone RIP

I was given a set of what I was told were UT inks that I planned to
use in an Epson 1160.  I ordered a few sets of new, empty cartridges
in anticipation of filling them with the inks.

It turns out the free inks are UT-2 for the six color printers.  

Can I use any of these in the 1160?  Perhaps omitting the light cyan
and light magenta positions?   I'm willing to experiment.

If so, which three inks go into what positions on the 1160 cartridge.

Thanks,

Larry
