Digital BW, The Print

I call the inkset I have in my 7500 the UT-FSN+.  It varies from the UT-FSN
in a couple respects.  First, the middle gray is darker.  In the FS-type
inksets the M (medium light) and Y (very light) inks have always been, in my
view, too close.  The gap between the M and C (dark gray) is very large,
however.  On the modern printers this doesn't make much difference.  On the
7500 it did.  So, this is a distinction between the inksets that doesn't
make much practical difference to the modern desktop hextone printers.

Second, The UT-FSN+ has UT-FSN in only the C, LC, and Y spots.  I put a
light warm gray (UT2-LM) in the LM spot, and, initially, PK in the M spot.

The light warm ink helps me profile the rag matte papers.  I think their
shadows often get too cold.  This ink also allows for a reasonably good warm
print on most rag paper, which print warm in the highlights even though the
Y ink is neutral-cool.

The PK continues this warm ink channel.  It also helps give a good dmax when
used with the C to generate the black.  Eboni is in the K spot.  Since I'm
not that interested in warm prints, I now have PKN in the M spot.  The light
warm gray still allows the profiling, but the PKN gives even a better dmax.

The UT-FSN inkset in the CMCMY ink order allows relatively easy grayscale
printing with the hextone printers.  A simple grayscale curve is all that is
needed.  Simplicity was part of that program.  

The UT-FSN+ is more complex -- almost a variable tone inkset.  So, I really
don't recommend others use it in a printer for which there are no ready-made
curves. 

Hope this explains the differences.

Subject: [Digital BW] UT FS & UT-FSN for Epson 7500 ?



Maybe Paul Roark can answer this question - we have talked about it before.
I see that MIS has released the UT-FS and -FSN inks for Epson 1270/80 /90
(six-color 
printers). Are these inks the same as you use in your Epson 7500? Or what is
the 
difference?
