Digital BW, The Print

I guess I would like to hear a layman's description from an ink chemist as
to what bronzing is and it's cause.  We know what the symptoms are but what
is it that we are seeing?  Apparently, the R800 exhibits bronzing and it
doesn't have a light black ink.  I suspect the causes of bronzing are
inherent in all the latest (non dye) inks we are using - either dedicated
B&W or colour.  (It is not just a B&W phenomenon and is visible in the
colour sections of UC prints - especially if you coat just a portion of the
print with glop to have a comparison.)  I don't know what sort of research
team MIS runs but they at least have a chemist who develops the basic inks.
Perhaps, given your relationship with them, you could get us all a better
basic insight into the issue.  The big benefit of a coating (as opposed to
an ink solution or glop in the mix) is that the reflectance of the printed
paper can be evened out as well as the bronzing "treated".  My bet is the
two are very closely related and that only a paper that can fully absorb
today's ink (a la dyes) will provide a solution better than a coating.
