Which is why I humbly suggest you not comment on products you do not have
experience and are only hypothesizing. That does not help the members of
this list.

Just because you can't get your head around the concept doesn't mean it
can't or doesn't work. I could go into detail on how the process works but
you could garner this from the marketing literature if you actually looked.
Better yet, why not try the product? Maybe you could learn something new for
your software product?

I am not contesting your background or experience in color science just
asking you to refrain on commenting products you have no experience with.
That does not help others on this list.

True, that was a leading statement that I didn't back up with a comparison.
I have worked with all the leading RIP solutions (it's my business!) and
never seen as tight match of a contract proof (or press proof) to the GMG
inkjet proof. But don't take just my opinion, the IPA proofing report
confirms what I have experienced with my own eyes. Sure the IPA report is
somewhat flawed but it's a better barometer than just one person's lofty
opinion on a process or product. Thanks for your comments and input, lets
end this thread.
