Am i correct in assuming that libtiff and IJG jpeg-6a does not support jpeg compression for cmyk images?

No, you are not. It should work. I say "should" because we've been unable to find any other implementations for cross-testing.

If you intend to exchange TIFF/JPEG images with other applications, you will need to discover whether those apps support the TIFF Tech Note #2 flavor of TIFF/JPEG.
