QTR-Quadtone RIP

In the absence of any answers, I took the plunge and installed the
MeasureTool, and have been charging ahead using the various QTR - i1
user guides.

Qu1:  I have had real trouble getting the MeasureTool to read the
Step-21x4-random.tif in strip mode.  First time round I kept getting
too many errors.  Second time (with the tif file printed with the
linearised curves) I had some success, but there were some rows where
I kept being told that the software could not recognise the boundary
strips.  Does this sort of thing happen a lot?  Are there any tips of
avoiding it? I tried just about everything.

Qu2:  I realise that you can convert the L values to density, but is
there any easy way to get the MeasureTool with the i1 to give density
readouts?  I'd like to be able to measure dMax directly, and some
posts that I've read here imply that you can using the MeasureTool and
the i1.
