Hi Kevin,

The AIMS are based on measured values of dMin (the plain paper) and dMax
(paper with the max amount of ink).  You just evenly divide the range into
the number of steps you want.  The tricky thing is that density is a 
logarithmic scale.  If you were to look at it in L* space (from LAB) it would
be mathematically linear and also linear in human perception.
