Digital BW, The Print

If we assume the nozzle-check pattern to be "honest", one could scan it and
compare it with printouts from different RGB patches. The obvious problem
being that the pattern is *thin*...

This is not a practical question; just a bit of niggling detail
curiousity.  Do you know through either driver analysis or microscopic
evaluation of the printed results that this puts down *only* cyan ink
in an absolute sense?  Or do you simply believe, as I do, that in
printing a large area of pure cyan, the driver has *gotta* use mostly
cyan ink?  

In terms of purging, in particular, there's no meaningful difference
between the two alternatives I mention.  But if you're using it to
measure a maximum density for a quadtone ink, for example, it may
matter, perhaps.
