Hi there
I know that there will always be a difference between onscreen and printed results. Although I would like to know what are the best settings to avoid a huge difference between the bright and colourful colours I get in InDesign when working on the file, and the final result CMYK-pdf that goes to the printing company? Sometimes difference is so big... 
Are there special Adobe (or other) tools to avoid this huge difference between InDesign workspace colours and CMYK-PDF?
And is it recommended to use for example the ColorMunki calibration for a MacBook Pro?
Thanks a lot!
Bob
