Hi Jon Cruz Its a pity Cairo doesn't support CMYK. I would really like to know how you can convert the colorspace of an svg file, I have exported a CMYK file exported from Illustrator but it has not retained its colourspace. AFAIK editing the xml colour tag in a text editor is the only way to get the svg file to include CMYK or spot colour info, please could you share your method of you do this.
For CMYK values, I had a writeup done a while back. http://codewideopen.blogspot.com/2010/10/inkscape-does-support-cmyk.html
SVG 1.x does not truly support spot colors, but internally a single-stop gradient has been implemented. I've not checked on the to-print workflow with those. SVG 2.x was adding better colors, but we'll need to code more to catch up with that.
Also... the CMYK/Spot color workflow is fairly simplistic and dated. We need to revamp the workflow to make it easier on designers to setup and use different target print workflows.
