Thanks, C. David for your suggestions.  I am working on creating a new profile and 
will get back to you when I can compare the way it prints out the targets and the way 
the canned Crane profile prints the targets.

One thing, the Epson 10000 is a pigmented ink set.  Epson introduced two versions 
of the 10000 at the same time -- a dye version and a pigmented archivial version it 
called the 10000CF (for color fast).   I believe over 90% of all 10000 are pigment 
based.  (you must have chosen the ink set at the time you first initialized your printer)
