Digital BW, The Print

Orange shift seems to be due to chemical contamination (Ozone) rather than 
exposure to light.

It is always the combination of paper and inks that determines the life - you 
can't predict what life any given paper and ink combination will have without 
doing the tests.

The problem with defining any archive life is that of course no-one has had 
an inkjet print lying around for 75 years!

To try and determine which ink/paper combinations last for longest we have to 
rely upon accelerated life tests, of which Wilhelm labs are perhaps the best 
known exponents:
