Understood, all very good points.  Perhaps I am being too
conservative, but I've just seen too many things fade to get
comfortable yet.

My concern goes beyond my own lifetime. I'm not so worried that I have
to answer for it, but that the customer has a print that lasts.  For
years I've done lots of portrait work, and many families treasure them
and want to pass them on to later generations.  Just recently I did a
portrait of the pastor of our church who is leaving, and it went up on
the wall in the library with portraits of others going back to 1886. 
That photo will be there indefinitely, and the room has a skylight. 
The pics don't get direct sunlight, but there is fairly bright
daylight all day and I assume there's a significant UV component.  I
made sure it was framed with UV glass.

The image didn't work well with BO so I used the modified UT7 I've
been working on, which has eliminated much of the non-carbon toners. 
So it's the best I could do right now.  I just hope there isn't a
problem years down the road.

Regards,
Clayton
