What is the best way to print a design on a trucker Cap / Hat with a professional look, without seeing through film etc?

I a drawing on my PC that I want to transfer on a white Trucker Cap / Hat and you want it to look like professional and not have a clear boundary around around him or letters, the letters himself.

Hmm. If you could find a way to iron on the hat without altering the design, there are printable iron on transfer paper. You can have more chance to take someone who does embroidery machine and embroidered with the design on the hat. It would be a look professional, and it is easy to modify the design to be exactly as you want.
