X6 Color Settings For CMYK Printing?

Does anyone know the ideal color settings for exporting .jpg and .eps files for CMYK printing? The default X6 settings result in rather washed out looking exports (both on the screen and on the prints). Black looks very dark grey etc.

Never had this issue with X3 but I understand that X6 uses a totally different color engine so I figure I just need to know the correct settings.

Thanks for any help!
