Exporting design in CMYK

[Albacore]

If you export it as PDF it will export it in CMYK which you can pass to your printer. As Steve has rightly pointed out jpeg. is not the format to use but this will depend on your card design. Talk to your printer and get a sample print of your card before committing to a large run as the jpeg might look washed out.

Keep in mind however that Xtreme 5 standard cannot export CMYK PDF nor can it import images using the CMYK colour space.
It can however export CMYK tiff and allow you to edit local colour in a CMYK colour space.

Xtreme 5 Pro however will allow CMYK PDF export and import
