Digital BW, The Print

I wonder if we're all talking about the same thing. My understanding is that
metamerism and "bronzing" are the same, i.e., a printed image viewed from an
angle (usually), displays a metallic-like bronze-tone in the darker ink areas,
creating an almost posterized or negative image in the worst case. Chromaticity
(as it explained to me by the Cone Editions lab manager) is when ink reflects
differing coloration, depending on the viewing light source... the coloration
usually being crossovers such as magenta or green. If I'm incorrect, please
don't hesitate to set me straight.

Subject: [Digital BW] Re: Imageprint for B&W


I have been using ImagePrint for some time on a 2200.  I see
essentially no metamerism when printing B&W. At 50,50 tinting, the
image is slightly warm, but nearly neutral.  In fact I see more
metamerism when printing B&W using PiezoTone Selenium Tone inks on
my 1280...yes, there is some very slight metamerism, although it is
not objectionable...with PiezoTone.  Metamerism is not an issue when
printing B&W with ImagePrint.  This is because yellow ink is not
used, and it is said to be the primary cause of the metamerism using
Ultrachrome inks on the 2200.
