Clayton,

>Here is a summary of these numbers.

I've double-checked my numbers and added the missing ones to the table.

>... BO Dmax for FS Black?

Assume it is about 0.04 to 0.05 higher than the RGB printing dmax.

Note that all the fade testing of the group was on a relatively late batch
of EAM, not the new EEM.

One problem with the dmax readings is that EAM and EEM from the various
batches I have are so different.  For example, the latest batch of EEM has
that nice white surface, but the dmax has dropped badly.  With the new EEM
(letter size) batch, the FS-K dmax is only 1.59 with Black-Only printing.
It's 1.54 with RGB printing.  (Both of these are for the 1160 and Heavy
Weight Matte paper setting and "no color adjustment.")  Printer types also
make a difference.  My 3000 with the "good old EAM" consistently produced an
RGB dmax of 1.68 (plus or minus 0.01).
