Digital BW, The Print

It has been my experience that all of the factors discussed play a
role and you can't sepearate one from the others. First, you need a
great scan or captured file, second you need good subtle inks. Third,
fine quality coating of the media. Fourth, you need a good
linearization of your printer and the tonal seperaton that a workable
rip affords. Fifth, you need a good dmax in the bottom end. Sixth, the
skills to work the tonal range in the mids and high values through
subtle control of a curves adjustmet layer. Seventh, there is the
amazing factor of localized dodging and burning to emphasize volumes.
Finally there is careful sharpening, if it is an image with texture.
Being able to co-ordinate all of these things is what makes a print
come alive. That's eight steps, I'm sure somone can think of 2 more. 
It is easier said than done.
