I made somes test with scribus Team, and some troube as been revealed in CMYK handling in Inkscape export.
If you have a pure black shape and export it in several format (AI, EPS, PS, PNG), only the AI export preserve the pure black. All the other result in a rich black (around C80%, M80%, 80%Y, K100%), which gives a 320 inking factor and we should not have more than 280 % in the worst case.
Can someone confirm this. I tested on Mac OS, and can do the test with linuxes, but not under windows.

How are you testing this? I'd have thought that png at least would use RGB rather than CMYK, so the problem may well come from whatever software is converting the RGB in inkscape's exported file to CMYK.
