Digital BW, The Print

Hi everyone;

I recently loaded my Epson 1160 with MIS FS inks. I then proceeded to
print a few files that I had printed last year with Piezo inks and
Paul's curves ( PzoRGB4.acv ) via the Epson driver. I was surprised when
these files printed out about 40% lighter then the Piezo ink prints. It
was my understanding that the MIS FS inks where about the same density
as the Piezo inks.

Am I missing something?

What curves are people using to print with the MIS FS inks and the Epson
driver ?

Thanks in advance.
