I want my blue to print blue and not purple

[Kevy Baby]

The only color profile to use is the printer's: there is no "magic bullet" profile.

How are you getting this image reproduced? Thousands printed either lithographically or digitally? If the former, you should be able to get a high-resolution color proof (often referred to as a Matchprint, but this name, like Kleenex, is actually a brand name that is oft used generically). If digitally, you should be able to get a First Article Proof - basically a "press proof" off of the machine printing the file.

Tell me a little more about what you are doing (how you are reproducing the image) and I can help you a little more.
