Thanks for that Paul.
As you mention purge patterns: recently I prepared some purge patterns
to be used with QTR. So you can exactly determine whick ink channel
should be purged. 
This .tif file must be loaded in the Calibration Mode of QTR and then
be printed.
The red channel of the image determines which ink to use (127: ink 1,
191: ink 2, ...), the green channel controls the amount of ink (255:
no ink, 0: max ink). Blue channel is always 255.
