I was once told that some of the "dye" inksets actually use a hybrid black that contains very finely ground carbon as well as a blend of dyes. The reason for this initially was to hold down bleed in text printing. The presence of carbon would explain some of the black "dye" ink stability we've seen in tests. Paul www.PaulRoark.com
