Digital BW, The Print

Ernst,

Couldn't the reason be that this paper is designed for color printing, and
the interaction between the color dyes/pigments and the receptors in the
paper can depend on a simple anionic/cationic interaction. So although some
might want neutral or buffered papers for max life of B&W prints, this might
conflict with the requirement to precisely localise the ink dyes/pigments
and to prevent them spreading, thus enhancing color detail.

Just a possibility, from what I have read.

Bob Frost.
