Digital BW, The Print

Martin, 

Remember, that's several years in normal room light without fading! 
About 3 months in a south window is all you can hope for with any
inkset.  However, it should be kept in mind, that nobody should ever
keep their prints or any other form of paintings/drawings, etc. in full
sunlight for 3 months, or even 1 month. 

Wonder what is in Acrylic paints that makes them so permanent? I have 30
year old Acrylic paintings that are as bright as the day I painted them.
