Once you've set the quark prefs as described you need to Export to PDF this will now make a .ps file
You will need to set details like font embedding and image resolution in the Export menus, or you can save all these as an Output Style (PDF).
Fire up Distiller, Select the correct Settings and drag the .ps file over Distiller. Ask your printer to provide Distiller settings if you are not sure which to use.
