Digital BW, The Print

Florian,

>I want to buy a MIS B&W System for my Epson 7600.

There are a couple of issues that you need to decide up front. 

First, do you like to print sepia, or is carbon warm enough?  I included
sepia in the UT2 and UT7 inksets, but now tend to avoid it. It has
significant amounts of color pigments in it.  As such, it is just not as
fade resistant as the other inks.  Additionally, most printers seem to be
smoother if all the color channels are firing.  With the sepia installed,
most of the curves do not use that ink position.  The UT-3D inkset omits
sepia in part to have all the channels used regularly.  I, frankly, find
pure carbon on Silver Rag is as warm as I need to go, and it's the more
lightfast pigment there is.

Second, do you use your large format printer regularly?  My experience with
blended B&W inksets (all I've tried) is that they tend to have tone shifts
if the inks are left idle for more than a week.  As an individual
photographer (as opposed to a service bureau), I just do not use my large
format printer that much.  As such, when I did us it, I had to purge the
inks that were in the tubes connecting the cartridges to the head.  This is
time consuming and wastes ink.  As such, I'm moving away from blended
inksets (more than one pigment type in the same ink, like carbon plus color
pigments) for large format printers.  

See my Oct. 1 message #80202.  The same issues would apply to the 7600.  So
far the new approach is working very well.  It does require a rip, but you
already appear to have such.
