It has been my experience, after more than a decade on the Photoshop forums (they were blissfully split by platform until recently), that any question that begins with "What is the best way to…?" comes from a user with little or no experience with Photoshop and/or color management.
I say this because of your assertion
The color management is know by me…
The truth is that you have absolutely no clue as to Color Management, otherwise you wouldn't even have asked your question in the first place, much less your response in post #2.
Please be more accepting and humble, and listen to the helpful replies you have gotten already.
Color Management is difficult to understand at first, and some folks just never "get it". It requires a lot of study. There are excellent volumes on Color Management by Bruce Fraser, Andrew Rodney and others. Look for them at amazon.com.
