You cant give a printer a RGB image and say just print this to this profile it should be fine.
Why not? That's exactly what the late-binding workflow consists of.
Inkscape creates and makes it graphics using RGB to render color. Using a Icc profile that you will link will change the values of the rgb colour and apply CMYK values to that colour. The graphic as far as inkscape is concerned is still RGB but uses the profile to convert the colour. So your early-binding or late binding method holds no value because
- Inkscape does provide a jobdefinition file so how can you claim to
have sent a print ready PDF, neither does it provide an option to convert colour to the linked profile at export. 2) your PDF is still in RGB staright out of inkscape, unless you have secret magic script that converts the PDF to CMYK.
Well, first of all, Inkscape does not work in "RGB" color. Instead it specifically works in the sRGB colorspace. http://en.wikipedia.org/wiki/SRGB
There are icc profile files available for that, but are not always required if one uses that as a base for RGB values. The common color mangement libraries out there have sRGB support built in.
Using an ICC profile *different* from sRGB will result in different colors when you go to print, *and* in different colors on screen.
The key point, however, is that outside of the context of a specific target CMYK colorspace, CMYK numbers are meaningless. However within the context of a specific CMYK colorspace, the same CMYK numbers should get you the same color no matter what printer you send things to.
More detail was in http://codewideopen.blogspot.com/2010/09/cmyk-is-meaningless.html
Often a corner print shop will have certain assumptions (often based on Adobe defaults) that gets things "close enough". It's OK if that works for you, but for more professional print work one should not rely on guesses.
