I recently submitted Inkscape generated marketing artwork to a commercial printshop (business card, rip card, etc) and was told to resubmit in CMYK 'space'. I was aware that this *might* happen, although some shops will print as-is. The Inkscape > Scribus > CMYK is not something I have totally 'grokked' yet, so because of a looming deadline, I used this site: http://www.rgb2cmyk.org/ .

I stuck with the default output (SWOP2006 Coated 300% V2), but I have no idea what the difference is between all those options. I checked the header of the converted image and saw the following:

... so I was pretty certain something good had happened. The printer accepted the images, and the final product looks great.

Has anyone heard of this site?
Any possibility that someone with some knowledge (and maybe some Adobe products) can look at the output the site provides, and tell us if there is anything to beware of, or any glaring red flags?

Take care, and thanks for the venue.

Hi gciii,
Just wanted to direct your attention to these 2 topics. The first is a new Inkscape extension, and 2nd is an announcement about a potential upcoming new feature, both providing CMYK print color.

Thanks, brynn. I'll be looking into those when I get a minute!

I'm suspecting http://www.rgb2cmyk.org/ uses imagemagick in the background, as it does this nicely from the command line:
