Digital BW, The Print

If the workflow is calibrated from your monitor to the final print 
digital negs can solve a lot of problems. But because of the analog 
components within that worklow there is a good chance that the prints 
are really bad if your print lab is a "thinking" provider. I made a 
try from color digital to 35 mm filmrecorder (you spoke of 35 mm in 
the initial message) to several analog hour and pro labs some 
with color negs and slides years ago and the results were, let´s say, 
"not so good" with an astonishing rang of color casts. On the other 
hand I began to print inkjet contact negs for my cyanotypes and they 
give me an amazing flexibility because my inhouse calibration covers 
all stages from monitor preview to final print in black box style - I 
don´t care how the negs look and my Cyanos don´t care that they have 
to show a rich tonality. But that are no 35 mm negs. If you´ve got a 
lab that prints digitally to paper you´ve a real good chance to get 
constantly fine results after some tests. The magic thing is that they 
have to do everthing the same way if they print your pictures. 
Otherwise you optimize, they counter-optimize and you don´t go 
anywhere because there is no consistancy. If the lab treats your files 
equally when printing you should get astonishing results after some 
circles in the test phase. 

Have fun
