Printmaking workshop.

Today Ling demonstrated the many security features found in currency to prevent forgery. These varied from water marks, micro text, a top to bottom window and so on. During the workshop, Ling showed us the methods of making these security features ourselves for our Digital Curency project. It was really facinating learning how this was done in combination with other technqies, proving very difficult.
