Hi Steve,

It's certainly possible to measure a wedge printed out with any method.
I'm also curious how to compare Paul's measurements to those I get.
The trouble is he has c,m,y density values, and the eye-one gives
Lab units.  It's similar tone info but I'm not sure how to convert
one to the other.
