Digital BW, The Print

Paul-

I've tried using the ABW mode in two different ways, although at this 
point I'm not even sure what it is intended for.  One posssibility is 
that it is a do-it-yourself-by-eye RIP intended to be set once (for a 
given paper and screen view) and left; the other is that it is intended 
as a tone-only image editing program to be adjusted for each print.  
The latter is ridiculous unless you are trying to waste paper and ink 
through image-to-image trial and error or you don't have PS.

I first used the controls in the first way, finding a group of ABW 
control settings that matched the screen.  The linearization was, 
however, poor at the "darker" setting, with a lot of compression in the 
shadows (last three or four steps of the wedge).

I am now using it with all controls neutral except for the "light" 
setting.  The light setting gives the least compression of shadow areas 
and a fairly linear print of an unadjusted step wedge.  To compensate 
this setup for the screen, I use a PS curve to view the file on screen 
and then turn it off for printing.  The results are pretty good, with 
accurate preview of highlight and shadow separations and a good 
portrayal of gamma.  It's far from perfect however.

So I don't think I've answered your question because I'm not sure what 
you mean by "density."  The ABW controls (brightness, contrast, shadow, 
etc.) do change the density of the print, but that can't be what you 
meant.

What Epson should have done is provide a Soft Proof profile of the ABW 
at standard settings, and the standard settings should not compress the 
shadow end of the scale.

So, thinking of a visit to San Francisco?
