----Yes. As long as you follow my earlier description of the differences 
between pure density reads (0.00-4.00) and "relative" reads (0-100%).

---- It should. But it could also be overkill, depending on how stable everything 
else in your system is day-to-day. You may prefer to have a standard file with 
a full tonal range and at the beginning of a new session, make a print and 
check it against a known Dot Curve. I mostly eyeball for grayscales and use 
the instruments for color.
