Digital BW, The Print

Oh, he was talking about gloss differential ( surface sheen differences between areas of 
the print)  and possibly bronzing ( of shadows ). Neither of these are metamerism, which is 
what I was asking  about. All pigments have the above two characterists t some degree on 
glossy media in my experience, even the hybred dye-pigment inkset of the 1280 type 
printers. I have never minded it on Premium Luster, even with my Epson CF inkset when 
sprayed.

And you guys are right, they need to be sprayed to reduce these relief effects, but that will 
have no effect on total print color. Anyway I'll check it out next week and see what I can 
come up with. It would be nice to be able to make monochrome semi-glossy prints that 
are neutral in color. I wish that new Lyson gloss paper that looks so much like gelatin silve 
paper would work with pigments. According to Lyson it doesn't. But, whatever.

My limited experience when printing with Photo Black and Epson Pr. Luster using
only the
two blacks(QTR-warm) was heavy metamerism of the light black such that when
viewed at
an angle, the mid-tones looked etched.
