Bronzing is primarily a problem on shiny papers in the black or near black
areas. If you catch the light just right, you get a faint yellowish
reflection. On Epson printers, it seems to be caused specifically by the
black ink, because ImagePrint, which uses a higher proportion of black ink
when making grays, produces prints with more bronzing than the Epson driver,
which mixes more color inks.

Your description would seem to match, although I hadn't seen it on matte
papers before. I consider it a minor irritant since, if you put a print
under glass, the normal reflections off the glass interfere with the viewing
more than the bronzing does. But I've heard that it can be lessened with
certain sprays.
