Digital BW, The Print

Thanks Mike,
OS is Windows XP SP3, QTR version 2.7.0.0

Also, my second calibration chart printed at "35%" does not seem any different from that printed at "100%"  
L values for K on the 35% calibration sheet are:
(going from 0% to 55%)  
24,21.2,19.2,18.3,16.9,16.1,15.9,15.7,15.7,15.5,15.9,16.2

similar to the L values of the K ink for the 100% calibration chart in my first post above.  shouldn't the values for the second calibration chart be such that there is decent seperation until the 100% step?  Instead I am reaching dmax around 35% again (just like in the 100% calibration chart)
