Digital BW, The Print

Yes. Epson Black has terrible metamerism.  Get the Enhanced Generations
4 Black from Media street. A beautiful black tone, and practically no
metamerism.

The black on the 1280 has metamerism?  I don't own a 1280
but on my 2200 the (matte) black is apparently the only ink
that DOESN'T have metamerism.  

Here's a question: Inks are pigments in a vehicle.  I own a 
collection of stone-plate lithographs that are about 100
years old and they have no metamerism and don't even appear
to have faded/shifted much in the last century.   How come
they knew how to make stable metamerism-free inks back in
1895 and a high-tech heavy R&D company like Epson can't
do it?

Because: 1. They didn't have to have them make varying droplet sizes.
	   2. They didn't have to squirt them through a little-bitty hole.

Yes, the black ink that COMES WITH THE 1280 PRINTER has metamerism. 
Don't know much about the 2200
printer yet.

That is a very good question. They probably used pure carbon back then 
for blacks.

Which is pretty funny in one sense, as metamerism generally affects 
pigment based inks more than dyes..

The black in the 2200 -- even being pigment based is less metameric on 
many media than is the 2200 black.  Just shows how far we've come in 
those 2-3 years.
