Digital BW, The Print

"What colour spaces were the respective files tagged as?"
--------------------------------------------------------------
The spaces are either Adobe RGB for an RGB file sent to ABW or a custom 
Dot Gain that I use if a greyscale is sent to ABW.

Sometimes I have sent the file to the printer with "Let printer 
determine colors" and sometimes per I believe Clayton's suggestion, 
with "no color management", but since my RGB files are always in this 
Adobe space, I am not sure that aspect makes any difference.

My latest print just a few minutes ago, came out decidedly with a green 
cast. I seem to have lost all the modest warmth that I would usually 
get with ABW +2/+2 on the toning wheel.

Discouraging.....
