Also, I think the conclusion of Livick's testing was that UK inks
had about a 25 million LUX life.
(A "good" coating could extend the life of UC 1000% or about 250
million LUX)
From Livick's data:
"A properly coated liquid laminate print fades out with roughly 250
Million lux exposure, so in effect you have ten times or 1000%
more "light/time" to play around with. It allows you to perhaps have
either brighter display conditions with slightly shorter longevity
times or much better longevity at the lower light intensities,
without the constant nagging fear of the print going belly up so
incredibly quickly. If you were to put a fully protectively coated
Ultrachrome print in the full sunshine, it would actually hold up for
about 8 months before the lux adds up to 250 million Lux causing
eventual failing. Of course without any protection at all, it's only
just over three weeks until it adds up to 25 million Lux mark and
degrades the image."
