This has turned into a rather interesting discussion. I am familiar with Dr.
Rich's work in this area and I have used this approach in the past. However,
I didn't really expect that anyone would be using this technique in a
publishing workflow.
For my needs, as I described before, I think a simpler solution would work:
I measured a process control strip at the time of printing and measuring the
targets for the profiles. Then, as time goes on, I periodically print and
measure the same control strip and compare to the original to see if the
printer has drifted. This is why I was concerned with using a different
spectro, since the measurements may not align entirely.
I don't really want to make new profiles if I don't have to, but I just want
to make sure I am still in calibration.
So what I'm thinking is when the iSis arrives, to run a control strip to
make sure I am in calibration (using the Spectroscan), then assuming
everything is okay, measure the control strip again with the iSis. This will
become my new baseline to compare future measurements against and I won't
need to change my profile (unless of course I am out of calibration for some
reason).
I know it's not perfect but I think that will suffice without all the fuss
of Dr. Rich's method, which is not trivial to implement into a production
environment. What do you think of this approach?
Thanks.
Ken
