Digital BW, The Print

Jenny,

About 18 months or so back, the issue of Portfolio Black fade 
resistance was discussed intensively on this forum. Try the search 
function and you may find lots of information. If I remember 
correctly, this controversy lead to the development of "museum" black 
by Piezography. A lot of PiezoTone users had switched their black 
inks to MIS Ebony because of this issue.

In short, this is old news.
