Vuescan is based on IT8 calibration, but it's hard-coded into the program 
and not something the user can do for their individual scanner. IME 
differences between examples of the same scanner are very small, so this is 
not a significant downside. However Ed did comment a while back that, as 
you'd expect, there's more variation at the budget end of the market. 
Paradoxically, cheap scanners would benefit more from individual 
characterisation.
