A quick gamut comparison between your newest profile and the Hahnemuhle supplied Photo Rag Ultra Smooth 305gsm shows that your new profile has approx. an 11% smaller gamut volume.
In my experience the ColorMunki generally produces profiles with at least the same gamut and usually wider than the 3rd party paper suppliers own profiles.
If you haven't already downloaded the Hahnemuhle Photo Rag Ultra Smooth profile, I would do this and see if it produces better results than your custom ColorMunki profile, if it does then there may be some issue with your ColorMunki Photo device or profile generation workflow.
Thanks for this. The paper I am actually using is smooth 308 gsm...rather than extra smooth.
Also how does one get one of those graphs?
I guess what I am finding frustruating is that it seems when soft proofing no matter what paper I use from glossy to matt, it seems like I will never be able to achieve bright saturated colours. The colours only shift marginly from paper to paper. I thought it may be my setup but now I am thinking that is the nature of these fine art printers. Even when I download profiles for other papers the colours don't shift that much.
An example is roughly what I am getting from Photoshop document to actual print setup area. The 'Match print colors' in the print dialouge box is pretty close to what I get in the final printed document...so I guess I am trying to figure out if in fact it's true that I will never be able achieve bright saturated colours or there is something else going wrong
I understand the bright green I wouldn't be able to get, but suprised I can't get some of the brighter reds.
