lightfast fade tests for soya and other process color inks?

Where can I find tests of how many years common process color press inks resist light fading?

Talk to Gains Ink - (800) 421-6167 - they talk about fade resistance on their website: http://www.gansink.com/process_inks.asp

Quote:

Lithographic fade-resistant printing inks, by industry standard, will hold color for up to three months of exposure to sunlight. The measure of this standard is eight hours per day of direct sunlight exposure in a midwestern sun.

Quote:

We cannot guarantee any inks for a period of greater than three months of sunlight exposure. Because we have no control over the many printing variables we cannot make guarantees even for shorter times
of exposure to sunlight.

Please note that process black and cyan are inherently fade-resistant, only the magenta and yellow will fade with time. Gans Ink’s fade resistant process inksets are formulated to wet trap inline, however, it is possible to purchase only the fade resistant magenta and yellow and run them with your standard house black and cyan in many instances.

Consult with your Gans Technical Representative to determine if this is possible in your specific application.
