Michel,

>I would like to modify UT7 inks to get a slightly stronger yellow. 

Do you use sepia?  Is it just the sepia you're trying to modify?  Or do you
want to have a warm tone, not sepia, but more yellow than the warm tones
currently are?

The Y cart is the open space that makes modifying the inks the easiest.  The
2200 easy refill carts facilitate this.  If you don't use the sepia, but
want a more yellow warm tone, just put MIS 7600 yellow in the Y cart and use
the blue curve to sprinkle it in as desired.  It has such a low density that
the other curves will probably not need any modification.

If you want a more yellow sepia tone, mix it.  The standard sepia toner in
the Y spot is basically 84% LC, 8% Y and 8% M.  You can alter the color
ratio to make a different tone sepia.  You could just add Y to the existing
sepia to do this also.

Hope this helps.
