Digital BW, The Print

Epson came out with a "white paper" on their image stability so I
guess now Kodak has to create theirs. Poor Kodak, they are loosing
every battle of the war so badly.

Kodak uses 120 lux brightness for their tests while Wilhelm and others
use at least 450 lux. Now Wilhelm isn't perfect we all know, but that
is a big difference in illumination for that time period of 12 hours a
day.

Here is a pdf explaing the differences between their tests. As far as
I can see Kodak is the only company that uses these methods and these
figures -
