Welcome to InkscapeForum!

Is this using the extension announced in this topic: viewtopic.php?f=11&t=5943 ?

but my error occurs on windows, does nobody create professional printing cmyk pdfs with inkscape?

I don't know, probably a few people do, but only using that extension (to my knowledge). And I won't be able to answer your question. If you did use that extension, you might get help by posting reply to that topic. Or I guess the developer must have included some kind of contact or support info with it.

I don't understand much of anything about that extension. In that topic that I linked, in one place, it says "all but one runs on Windows" and in another place it says "doesn't run on Windows". So I'm not clear if it runs on Windows or not.

And neither am I clear whether you even used that extension.

If you didn't use that extension, then I think a lot of people would be interested in how you created a CMYK PDF with Inkscape. Inkscape, without that extension, cannot produce true CMYK, on any operating system. Or did you somehow get the CMYK in the PDF by passing through some Adobe product?

good bit of discussion about this in the posts

it seems to be too a question of what you think "professional" is

I have had some luck with opening my svg in scribus and using that to write the cmyk/pdf file, you don't want to have to complicated of a graphic.
If you need something complicated maybe you can use a cmyk/tiff ? There is some utility to make them, or maybe it's a gimp plug in I forgot, sorry.
