security aspects and difficulty of printing money

Please provide a 500 word essay of the security aspects and difficulty of printing money. How exactly is money produced? What are the many different techniques used to provide security? What kind of press and why? etc….. This should be an original “reaction” paper in your own words. I will not accept any papers that have similarities to others. I expect a word document not shared on google Doc. A 500 word essay is one page single spaced or two pages double spaced in a 12 point font.
