Sorry but I canpt see a logic in your question, it sounds like "What kind of vegetable should I cultivate to reach Mars with a bike?".
However… If you calibrate your plates accurately (every brand of plates, according to your RIP and your platesetter), you don't need to change anything in you color proof workflow.
That's the standard.
G:
The company that I work for is thinking about going to Fuji plates. We have used GMG color proofing (10 years +) with Epson Stylus Pro 9900 with SpectroProofer. One option would be to keep GMG the other would be to go with Fuji’s ORIS.
Would like hear pros or cons.
Thanks!
