Digital BW, The Print

Jean-Marc

I think the point is that if you want to do curve/tone/etc. adjustments in PS you need to be in 8-bit mode.  Once you are in that mode, there is no point in converting back to 16-bit mode to print as you gain nothing.  The additional 16-bit data is already lost and your prints will look no better converting to 16-bit to print than if you left them in 8-bit.

Of course, if your scanned images need no adjustment then print in 16-bit.

  I don't think so.

  If you use Piezography BW plugin (which is a driver replacing the 
  Epson one), it is strongly recommanded to keep as much information as 
  possible (the highest dpi and the highest bit rate). 

  That's probably the reason why Jon Cone upgraded its Piezography BW  
  plugin (to a version 6 which works with 16-bit files) and why its Pro 
  version of Piezography handles also 16-bit files: I do not know the 
  technical reasons and if there is really a difference between 8-bit 
  and 16-bit files for printing (may be its a pure commercial argument).

  I had tried in the last months to initiate a thread dealing with the 
  esthetic differences between 8-bit files and 16-bit files printed via 
  the PiezographyBW plugin (see the piezo3000 newsgroup) with no clear 
  answers.
