Digital BW, The Print

In my original post concerning the comparison of Piezo prints and 
Epson (driver) prints my chief concern was with what difference could 
be _perceived_ between prints made with the two drivers, given 
identical printing conditions. To be sure, "objective" tests require 
repeatable methods, but anecdotal accounts count for something too. 
If a dozen reputable people tell me that they can or can't perceive a 
difference in revealed detail between prints (MIS VM quadtones vs. 
Piezo quadtones) made by the two drivers, then I think it's worth 
paying attention. We can then go on an look for "objective" 
verification, along with some kind of explanation.
