Digital BW, The Print

I am newcomer to digital printing and do not have much experience
with it. Unfortunately, I have never seen a good (or bad!) digital
print. I am overseas right now.

I was wandering what exactly is metamerism? How do you define it? And
does it manifest itself differently in color than in black and white?
I just read on this forum that dye inks don't have metamerism, but
pigment inks do. Why? Does metamerism  exist in traditional wet
printing techniques? I have never come across this term until diving
into the digital printing world.

I hope these basic questions won't bother you who are beyond defining
metamerism, but who rather trying to get around it!

Thanks for your help!
