See here:

search on the page for "CMYK", I posted some code in the middle of the thread
to add CMYK JPEG images.
I'll also add that code to JPEGFactory soon.
Converting a BufferedImage from RGB to CMYK may be possible (we do the opposite
in {{PDColorSpace.toRGBImageAWT()}})... but I can't remember that this has been
done before.
It is unclear to me what you want (maybe both :-) )

> It is necessary to form a PDF document, which in the future will be sent to
> print the company's printers. There are several ICC files provided by
> companies for printing.
> I have RGB images that should be in CMYK after adding to PDF.
> My code is now for drawing an image:
> ImageObject = LosslessFactory.createFromImage (document, image);
> ContentStream.drawImage (imageObject, position.x, position.y,
> imageSize.width, imageSize.height);
> I'm wondering whether it is possible to display images in a document in
> ColorSpace CMYK? Unfortunately, I'm not find working examples yet.
> If so, how can I get PDImageXObject in CMYK ColorSpace from BufferedImage in
> RGB ColorSpace?
> When I try to create PDImageXObject instance from CMYK image file I get
> exception:
> javax.imageio.IIOException: Unsupported Image Type
