Actually Quadtone is partly GPL, because the printing part is Gutenprint. The rest is shareware. Real "arty" B&W is usually in fact achieved with Duotones (two colors) which are highly tailored to an inkset, and thus I would strongly recommend you look at Quadtone RIP which already has the hard part predefined As Alastair points out, Gutenprint can be very nicely color managed with Argyll; a bunch of people use it this way, there is no big difficulty apart from setting up the media and print options, and Argyll is a very good RGB profiling package. Alastair make Photoprint, which I believe can handle all the color management specifics. I'm sorry, I won't talk about my own workflow here as it involves a number of experimental tools, and proprietary packages. But I'm quite certain that Argyll can effectively profile RGB print processes, and I'm equally certain that Gutenprint can produce very good output.
