Antonis,

I guess I am wondering if you printed out a step wedge containing the 
13 values in the Custom Dot Gain curve dialog box, could you then 
measure them off the print with a densitometer and then calculate the 
appropriate values to enter into the Custom Curve? And if you can, 
would it give you any greater boost in screen-to-print calibration 
accuracy then just eyballing it?
