QTR-Quadtone RIP

The simple answer to your question is that yes, most any densitometer
that reads reflected densities will do.  There are lots out there on
e-bay, and virtually all of them will do the job.  Even an old analog
readout would do.

It is possible also to do this with a scanner.  However, you just
about have to use a standard BW stepwedge calibration target in every
scan to get even semi-reliable results, and even then you end up doing
a fair amount of manipulation to get smooth and predictable results in
your printed results.

Once you get the hang of it, producing new curves with the help of a
densitometer is pretty easy.  The hard part that I found was figuring
out how to tweak the individual ink curves, in order to get close
enough that linearization would work.

Hope this helps,
