Digital BW, The Print

I just measure the steps and cap the inks where the density more or less
levels off.  As Daniel said it is not too critical.  But in the pursuit of
maximum density you will likely want to use as much ink as possible without
overloading it (hence I use he densitometer rather than a visual).  Don't
forget to then reprint the calibration page with the ink limits in place to
determine the partition values.  But again they don't have to be absolutely
perfect as you get to linearize as the last step.
