James,
Some of the differences between the 5000 (dye based inks) and 5500
(pigment based inks) are things along these lines.
The Epson dye based inks only last around 20 years and are more
susceptible to fading in sunlight and exposure to ozone. Prints
from these types of devices take about 24 hours to become stable for
profiling and viewing. The term I hear used to describe these color
changes is dry back. Also prints from Espon 5000, 7000, & 9000 (dye
based ink) printers have richer blacks and a longer white to black
range than the Espon 2000, 5500,7500, & 9500 that use pigment based
inks.
As for the Espon pigment based inks, they are supposed to last around
200 years and are not as susceptible to fading in light etc. These
inks take ten minutes to become stable for profiling, but have a more
apparent metamerism effect than the dye based inks. Metamerism is a
phenomenon where two objects or color images look exactly alike under
the same light source, but when viewed under another light source,
one of the objects changes color. This means that if you want to see
more consistent results you should view your prints under that same
light sources.
I find that each of these devices are straight forward to profile
with little problem and from other comments on this list others have
the same experience.
Cheers
