UT7 (which was basically UT2 upgraded for the 2200) had sepia in it and varies the tone up and down the Lab B (yellow - blue) axis , with no control over the Lab A (red/magenta - green) axis.  UT-3D drops the sepia and adds Lab A control.

The UT2/7 sepia has a lot of MIS yellow and magenta in it.  It's fun to play with, but not very lightfast.  I dropped the mix mostly due to the lack of lightfastness.  It just was not up to the standards I thought we ought to have to avoid the old prejudices against inkjet printing.

The 3D inkset's adding of the Lab A control gives the most control, but it's more difficult to profile due to this new variable.  One ofsetting advantage is that it can be profiled by the ColorVision system for neutral prints.  With the Epson driver, however, getting away from neutral is a problem.  The gray substitution of k3 printers is such that one loses control via PS curves.  QTR is much better if manual control and something other than neutral is wanted.

Hope this helps.
