Digital BW, The Print

I thought some of the folks here might be interested in a bit of test 
data that we ran this weekend.

I printed out a 21 Step Tableb on Epson Archival Matte and H. German 
Etching using the Piezo inks, MIS FS spectrum inks on my Epson 7000. 
We then let the strips dry overnight to obtain dmax. The strips were 
read on a MacBeth reflection densitometer.

As a comparison, we also read a platinum print made on Cranes 
Parchment using Potassium Oxalate contrast mix #3.

MIS FS -   1.70
Piezo  -   1.60
Platinum   1.55

As a baselin comparison, Epson OEM dye inks resulted in a solid black 
with a dmax of 1.9.

The density difference between HGE an EAM was around .01 (negligible)

One thing that I neglected to mention was that Gordon Brown and Tom 
McCartney plotted the H&D curves. They are basically identical for 
the Piezo and MIS FS inksets.
