摘要
The invention relates to a high security film, optionally in the form of a slit thread or a micro tape, which is then inserted into high security paper such as a bank note paper and the like during the paper making process. The invention envisages a novel method of producing such a high security film using a print transfer method, wherein one or more security features are incorporated on one or more indicia including letters, optionally graphics, during such a production process, using multiple printing stations and lamination.
