Hi Jim,
I understand what you are saying and know that this can work. However,
there are several questions.
1. Has Gracol published CIELab colormetric targets for their standard?
Have the TR004 measurements been certified?
2. Do you send a custom profile to your client to make their CMYK
separations?
3. Or do you send them a "standard" profile?
I assume that you are running the press to certain density, and dot gain
standards before you profile the press. However, I have found that you
can still get wide colormetric variations even when running in
specification. There are so many variables on press. I found that a
Speedmaster 74 has a measurable variation cycle of 4 sheets. You could
see a 4 sheet cycle due to the ink train. Of course there are longer
cycles having to do with speed and temperature changes over time and
length of run. I just found that the press is not a very consistent
target. Laminate proofs are much more consistent.
You bring up another interesting topic as well. Do you print to a
standard or do you try to print better to your own inhouse standard? If
you set out on your own you have to send a custom profile for the client
to make their CMYK seperations.
Seperations = Proof = Press
If they are all done at one location there is no problem. However, if
not, you have to work to a standard.

This is a common strategy for setting up an inkjet proofer, that is you
create a costlier proof as your target. And IMHO not a bad approach.
However, if you are printer you have another option of getting the press
under control and creating a press profile. Then use that press profile as
your target for the inkjet print.
Another thing to consider is using the new Gracol 7 methodology that takes
advantage of the ISO specifications for things like ink and paper, a
standard press setup and a Gracol certified consultant to get your printing
system standardized. It will cost some money to get setup and trained and
so a company has to decide what it is worth to use G7 to help you attain
very good color matches between the press and proofing system.
Also there is the Gracol Master Printer program. Once you become qualified
as a Gracol Master Printer then you have an opportunity to differentiate
your company from other printers. This potentially makes your printing
services more valuable. Or at least that is what I understand and believe at
the moment.
In the scenario I am putting out here, the press is the target in all cases.
While mileage will vary, the new G7 method makes press calibration and
inkjet proofing very interesting and do able at the printers site and at
their clients remote locations.
