Hi Randy. I also enlarged the calibration target, specifically so that
I could use it with a lab type bench top spectro. It worked fine.
I think all that is required is that you not embed any profiles into
the target or alter the actual target image's numbers in any way.

I also made a large patch version of a 21 step grayscale similar to
Paul's version to use for the linearization process. You don't print
the 21 step target in calibration mode.

Regards,
Duane
