Digital BW, The Print

If you print with color inks, sooner or later one of those inks will
begin to fade. You will then get a color cast in your print.  And don't
believe what you read about longevity, these inks can and do fade very
fast in certain locations, and heat/light/humidity conditions.... The
2000P printer inks displayed very noticeable fading in 6 months in a
west window in a photographic studio in Mayville North Dakota. And they
were supposed to last a hundred years with no noticeable fading.
