I suggest everyone who is interested in ink fading (and I'm assuming 
that's eveyone here)go to this archived page to download Livick's fade 
testing data and keep if for reference.

This will come in handy in handy for your own testing, if you choose to 
go that route.

It also can be compared to other's testing results, such as the 
recently posted Nanochrome "test".

Livick has some conversions he gives to use a light meter or your 
camera meter to check for LUX amounts in a giver situation.

Also, I think the conclusion of Livick's testing was that UK inks had 
about a 25 million LUX life with a good coating. Whether you give it 
all in one day, or spread out over hundreds of years.
