One day, while he was repairing the wire of the speaker by soldering iron there was a golden foil lying near him. He kept the golden foil on the leather and wrote his name with the soldering iron on it and found that his name was embossed in golden fonts on leather. This gave him the idea to search for a pen which could do this embossing work. He first experimented with a soldering machine and foil on a piece of rexin. When he saw this experiment being successful he searched on Google for existing machines and found that there is one machine, a plotter of company named Graptek could be used for his purpose. He found one unit with help of a family friend.
