Craig,
Did you measure the exact same number of patches with each printer?

Subject: Epson i1 profiles
I am fairly new to this list-serve with one prior question outgoing
and a few responses contributed. I work as a commercial photographer
with a high interest in good color management practices. I am
working in a calibrated and, for the purpose of this discussion,
closed-loop workflow. Having just acquired a used Epson 7800 printer
after using my trusty Epson 7600 for several years, I generated some
new paper profiles for the 7800. I use an i1 spectrophotometer and
have been very satisfied with the results, also for several years.
It is my understanding (this may well be where I'm going wrong) that
the 7800's K3 inkset was designed to have a larger gamut than the
older Ultrachrome inkset. The new pigment inks also addressed some
B&W printing issues along with metamerism problems.
When I compare the profiles I've generated in the Apple Colorsync
Utility for the two printers, from the same media, the new profile
shows as significantly smaller than the older 7600 profile in almost
all areas. This is true of the Somerset fine art paper comparison as
well as Epson Enhanced Matte paper comparison. This seems counter-
intuitive because it would indicate that the new inkset is less
capable of the extremes of saturation and density (gamut), not more.
Am I missing something? All profiles were generated at least twice.
I don't use profile editing software.
Regards,
Craig.
