We have a Barbara Kruger photo engraving on magnesium in the
collection which incorporates red pigmented relief ink.  I am
wondering how light sensitive this inks is and what a good resource
might be to look up the fading potential of other materials.  I have
the Light Damage slide rule put out by CCI but they discontinued the
poster (Put It Where the Sun Doesn't Shine- no, I am not kidding)
that gave examples of media/materials.  Can you help?
