I haven't done a thorough comparison of the two systems but sofar it
appears they both produce very excellent results. There is though one
issue related to dmax with IJC/OPM which Joe Berndt is working on.
He's working on some special algorithm to boost the dmax of the old
1160 printer. I'll let Joe make the announcement when he's ready.

Both software are very easy to use. You got a slick UI with IJC/OPM
but with QTR you don't even have to mess with the creation of an
initial ink curve, just print, measure, and fill in a couple of values
in the UI and you got curves, and of course both systems have
linearization steps.

Stephen Billard's QTRGui is making QTR very user friendly like
IJC/OPM. There are though two improvements I'd like to have in both
systems:

1. In QTR: something like "print target for linearization". I made the
mistake of printing a target for linearization with linearization info
already included and got terrible results until I got it figured out.

2. In both: a custom brightness curve. IJC/OPM has an Aim Curve but
I'd like to have the ability to add more control points.

Overall I'm very impressed with both systems as they both produce
excellent profiles.
