Digital BW, The Print

Bronzing and metamerism are not the same.  Metamerism is the 
apparent change of image tone under different light sources, such as 
incandescant lighting and ambient window lighting.  B&W prints made 
with color inks on the Epson 2200 using the Epson driver suffer from 
metamerism.

I print B&W using ImagePrint on the 2200 using matte papers and 
matte black ink.  No metamerism, no bronzing.  Bronzing typically 
occurs with glossy papers, which I don't print on.  Others will have 
to address this question.
