Hello Paul,

I just ran swab tests of the UT FSN inks compared to FSN inks.  I 
found that the UT-FSN inks have the slight magenta tint (to naked 
eye) while the FSN inks are slightly blue/cyan.  Is this part of the 
ink design to give more of a selenium look?

And now for the mild dismay:

I happened to have some old MIS GP (glossy pigment) inks designed as 
replacement "UltraChrome" inks for the 1280 class of dye printers.  
These inks have been sitting around physically undisturbed for ~6 
months.  All color inks show a dramatic sign of settling.  There is a 
translucent (but colored) phase sitting atop an opaque phase of the 
same color.  The photo black does not seem to show this.  I have 
never experienced this before, even with the older pigments that have 
sat much longer.  So, is the colorant in the FSN inks likely to 
settle over time?

UT, UT2, and UT FS users, have you noticed settling?

Regards.
