Digital BW, The Print

If by "free of metamerism" you're thinking that prints appear to have the 
same tone under daylight and tungsten illumination, then no, the Lyson 
Quads are not free of metamerism.  Moving from my "daylight" fluorescent 
light to a pure tungsten light, there does appear to be some slight change 
in tone.

I've come to the conclusion that the actual "tone" of an ink depends quite 
a bit on the paper it's printed on.  Most of my Quad Black images were 
printed on Legion Photo Matte paper.  On that paper, I'd say the images are 
pretty much dead neutral under my daylight source, and very slightly warm 
under tungsten.  I certainly wouldn't call it a purple tone, maybe just 
slightly brownish or reddish.  But there certainly could be different 
results with a different paper.  Personally, I don't see any particular 
tone when I'm looking at the pages under tungsten light, but if I view them 
under daylight and then move to tungsten I can see a difference.

I hate to say it, but after playing with an Epson C84 (there was a brief 
window this summer when a store discount plus two rebates brought the price 
down to $23 delivered) and MIS EZ inks, I've decided to print this year's 
Christmas books with that system.  It's not nearly as fast as a Canon, and 
the prints don't have quite the resolution that the Canon/Lyson prints do, 
but the tonality is wonderful and the pigment inks ought (he says 
hopefully) to last longer than the Lyson dyes.. At least that's my thinking 
at the moment.

Cheers,
Kip
