Digital BW, The Print

Hello All,

Several posts recently made reference to Wilhelm ratings for K3 ink on
various papers, but the numbers they quoted were for color prints. 
The numbers for BW prints using ABW mode are much higher.  The ABW
numbers are on page 3 of this report for the 2400

In summary, depending on the paper:

  Framed under normal glass: 110 to >205 years
  Framed under UV glass: 110 to >300 years
  In dark album storage: >200 to >300 years


Regards,
Clayton
