The formula change was just a minor change in ratio of cyan and magenta to
get a better average tone over a number of different papers.  The basic
formula remained the same.  So, I don't think the version of UT you are
using would make any difference (assuming it was mixed correctly).

The LM is very dilute.  That could be one of the factors involved.  I'm just
not sure what could be causing the trouble, however.  MIS has some
accelerated separation tests they can run.  I'll see if they have subjected
the full inkset to those tests.
