The head stage is used to focus the head (roughly) on the very varied thicknesses
of flexo media, it is also used to measure the thickness of each plate as it is loaded
so that distortion calculations can be done correctly. When installed, the hstage moves
to the away position and at that time this paramter is automatically updated.
From that point on, this position corresponds to the drum surface, and by knowing where
the head stage is after it zero's on a piece of media, the media thickness in steps can
be calculated.
Changing this value without re-zeroing the head on the drum (using "stage install") will
affect measured media thicknesses and therefore image size.
