">A corollary of what we've been saying here is that "Printer Manages

...personally I have not been bold enough to hit the 'printer manages' button yet!
We are still talking about a colour managed workflow using custom profiles (ok - occasionally the canned profile) via Application managed colour and the printer vendors OS/RGB driver. In other words what we get when we print carefully through photoshop and the Epson OS driver with our profiles.
Rips like Mirage and Overdrive use the same route - but with a far better front end and I've been told, off list, that some other RIPs using RGB drivers use the printer manufacturer's more adjustable SDK version of the driver rather than the OS - I need to test those becuase in the past I found some which claimed RGB drivers still gave less pleasing results to the OS driver
The issues I've had with some rips was not the colour per-se, but the screening and break up in the gradients. It is an issue driven partly by colour though in my opinion...
...for example, if you print a pure blue gradient via the Epson canned profile for their Premium Semigloss paper, it is evident (to me at least) that some 'purity' of colour has been sacrificed in order to achieve a smoother gradient (versus my custom 'colour accurate' profile). Perhaps this is where photographers are at odds with the graphics world? i.e smooth transitions of colour and tone vs absolute colour accuracy? After all, a toned (or duotone) image is often favoured over a purely neutral one in for this reason.
RIP manufacturers naturally concentrate on colour (often in blocks) hitting precise Lab values whereas the inkjet manufacturers know that photographers are interested in balancing colour against a more subjectively pleasing smoothness.
We now print lots of fine art photography and lots of short order graphics work, so I need the best of both worlds! I might have to run two types of workflow but it is the more complex nature of PDF's, Fonts, imposition etc that is driving the need for automation and a production rip.
Thanks for all the suggestions so far - I have some good leads to follow up and always interested in hearing more.
