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. > > > > I agree, but CMYK is not covered in the svg > > standard.

Thanks John Culleton, My current work around is to do just that or in most cases I change the colourspace of the pdf (including and especially images) using moonshiner. It doesn't always not retain CMYK colour values for vector objects, it is an extra step I would like to avoid. I was wondering if anyone else has been successful in using Ghostscript to convert the colourspace of a PDF, but integrated into the export dialogue maybe as a plugin. Its a slight hassle to import an SVG file, update the CMYK info on each object,export to PDF, send the file to my local printer, do a proof print with them, change the colour again in Scribus, export to PDF. I guess I will just have to continue along this way of doing things, until I have figured out how to what I want myself :) Please forgive if this email looks odd, I'm still looking for a mailing list reader to respond to posts on the list.

For CMYK values, I had a writeup done a while back. http://codewideopen.blogspot.com/2010/10/inkscape-... 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. -- Jon A. Cruz firstname.lastname@example.org
