I wrote an online system which creates high res images jpegs which go out to a printer. It works well, but the printer needs to receive CMYK images.
I'm having trouble finding documentation on how to create my jpegs in CMYK. Does anyone know how I can go about doing this?

The .NET GDI library does not use CMYK color space. It uses ARGB. That said, you would need to convert your colors from CMYK to ARGB.
There is an example of how to do this here:
It's written in C++, but you should be able to understand the general algorithm that is used to accomplish this.
There are also some other 3rd party tools, if you rather go down that line, that support CMYK drawing.

Ok, I see how to convert the colors to the CMYK values, but I'm not sure how I would actually save the file as a CMYK file. Is there something I'm missing?
