I am getting into sublimation printing, still researching and learning. But, one thing I have learned is with the ink I want to use I need to use a program that supports ICC profiles.  I've been told Inkscape doesn't support this.  It looks like there might be a work-around by using Scribus, but it would be additional steps.  I can't find much on the topic that's not in an old post (when I Google Inkscape ICC profiles).

Is this possible in the newer version of Inkscape?  If not, is it in the works?

Thanks

CMYK is a large undertaking:

Inkscape relies on Cairo for rendering. It’s a great 2D vector graphics library that simplifies lots of things for developers and provides some rendering speed-ups for users, as well as modern antialiased graphics.

The problem with Cairo is that it doesn’t yet support CMYK, or, to put in in a more technical language, it doesn’t yet support color management, color separation and spot colors. This is not because Cairo folks are not interested in that, but because they don’t have a dedicated developer to work on it, and it’s a lot of work.
