Digital BW, The Print

I think Carl is correct that there is dye in Portfolio Black.  If the
problem was some kind of gas attack, that would cause the discoloration to
be even on the parts of the canvas that were not exposed to bright light. 

I must confess that I cringe thinking of a hybrid dye-pigment print being
shown in galleries.  Trying to get the reputation of B&W inkjet prints up to
where high end galleries will accept them requires, I believe, prints that
have as much carbon as possible, and no dyes.  Cone's Museum black is a pure
carbon black that should hold up fine.
