In 1995 we tested the light fading stability of Indigo prints made
with an Indigo E-Print 1000 machine and, using our standard test
methods, the prints had a predicted display life of approximately 12
years before noticeable fading occurs when displayed under glass
with 450 lux cool white fluorescent illumination for 12 hours a day.
This was generally similar to the light fading stability of Kodak
Ektacolor chromogenic color negative paper of that era.  Refer to
our web site <URL:http://www.wilhelm-research.com> for additional
information.  We have not tested Indigo prints made with more recent
toner sets and these early data may or may not relate to current
products.

Although not tested, the dark storage stability of Indigo prints is,
depending on the paper used to make the prints, potentially very
good. Hope this is of some help,
