Good.  I don't know what accounted for the higher density prints I just got
out of my Piezo 1160 outfit.  I think I'll just assume that the densities I
was accustomed to in the past from Piezo and the FS densities are correct.

This is interesting.  With the original Piezo I have used with the 1160, the
black ink appears to be the same as the MIS VM/FS black.  They both result
in linear curves with the Piezo software and MIS VM curves.  However, Jerry
Nevins believes strongly that Piezo uses a black ink from Cabot.  I suspect
this is where the MIS "Double Density" ink comes from.  While it is not a
co-solvent ink like Piezo, it does have the characteristic of compressing
the blacks.  It makes me wonder if Piezo black, at least for the 7000, is a
different black than the original Piezo and VM/FS black.

My next project is to finalize the formula for a neutral ink.  I intend it
to be used as the base for sepia toner VM inkset as well as for a neutral FS
inkset.  I assume MIS will produce it if there is demand.

Paul-

Is it safe to switch carts from FS to VM without a flushing cycle?

thanks,
