Digital BW, The Print

Tyler,

I know you have seen a lot more of this stuff than I have, but the 
small collection of Piezo and MIS VM prints I have show the reverse.

There is a green tone in most of the Piezo prints (paper independent) 
that is especially noticeable under tungsten and halogen lights but 
shifts to neutral in daylight. An unpleasant metamerism. The MIS VM 
shows no green tone and behaves normally in moving between different 
light sources. Warmer under artificial and cooler in daylight.

Am I just seeing some ink batch variations?
