Digital BW, The Print

Rodrigo,

In theory you should be able to get better, smoother tonality in your 
prints by doing all the work in a 16-bit space. In practice this is 
limiting in Photoshop since most of the features are available only 
in 8-bit space.

It is possible to work in 8-bit space and transfer the key 
adjustments to 16-bit space which some people do. Up until the last 
release of Piezo they were forced to drop to 8-bit at the end in 
order to use the old Piezo driver.

Practivally speaking I have not seen any discussion yet as to the 
advantages of printing from 16-bit space vs. 8-bit. You can also 
print from 16-bit space using the Epson driver.
