Firstly, can I ask what you mean exactly by 'presentation'? 'Presentation' in English means that you are giving a speech or a small lecture to an audience, perhaps using Powerpoint or something similar. Or do you mean 'introduction'? That's when you meet a person for the first time. I'll presume that you mean 'introduction.'
An introduction might go like this:
Your colleague says to you: Claudio, this is Peter.
You say to Peter: Hello, I'm Claudio. I'm pleased to meet you.
That is fine for a formal situation. You could also say 'It's nice to meet you'.
In formal situations, people sometimes say 'How do you do?', but this is a little old-fashioned nowadays. By the way, 'How do you do?' isn't a question - the response is the same : 'How do you do?'
I hope that helps. Please ask if there's anything else you'd like to know.
