That certainly improves consistancy, but I've yet to see it beat custom 
profiling. Another reason HP does this and Epson does not, is that Epson's heads 
are permanent, while HPs are replacable thus in need of site recalibration). 
Epson provided (in some sections of the world) a utility that let users adjust 
the printer calibration with an external patch reader, but has hesitated to put 
much weight behind the method. And while its useful for making two printers of 
the same model run from the same profile, its not really necessary to get 
good results on a given printer, a custom profile pretty well covers that.
