Please see the test conditions below.
Lightfastness Test Conditions
1. Under fluorescent light (indoor display condition) with glass mount
2. The data is calculated by EPSON's accelerated test and does not mean
EPSON guarantees periods
3. The estimated longevity does not indicate the colour changing and
the durability of the paper itself
The lightfastness test is a simulation of colour fading in an indoor
preservation condition under fluorescent light with glass mount. The
display life may vary depending on the conditions that you display your
prints. Factors, other than light, such as ozone, temperature and humidity
can affect the print life.
