Digital BW, The Print

I have an image I've been playing with this evening.
Seems that any way I approach it, once I go to print it 'solarizes' 
and I haven't a clue as to why.

I am printing in RGB with the warm curve for 1270.
The tone are tight as it is and on the darker side.
Tried working from RBG scan to greyscale and back.
Tried working from Greyscale scan to RGB and print.

Little miffed at this point.

TIA for comments/guidelines,
