Hi John
Before you go too far with your  color experimentation it's better to check 
with your print shop, get some proofs of your basic experiments for 
comparison, ask the print shop's advice, etc, because what you see is NOT 
what you get when you export from screen to print, unless you're using 
something sophisticated and horribly expensive like PS (and even then....)
