I've always been curious...is there any relationship between the way 
the ink is laid down and the potential longevity of the resulting 
image?

It seems that the general strategy is to combine the different ink 
densities at a rate that creates the optimum printed density while 
achieving smooth tonal transitions and minimizing the appearance of 
visible dots. But should any consideration be given to the fade rate 
of each density of ink? Unless each ink fades at exactly the same 
rate, won't different curve shapes result in more/less-even fade 
shift 1, 10, 20 years from now? 

Thanks for any insight,
Peter.
