PRINTING MATERIAL WITH PROTECTION AGAINST FORGERY WITH THERMALLY TRANSFERRED PATTERN, SPECIAL FOIL FOR THERMAL TRANSFER AND MANUFACTURING METHOD OF SUCH MATERIAL Russian patent published in 2015 - IPC B42D25/30 G09F3/02 

FIELD: printing industry.

SUBSTANCE: invention proposes a printing material with a thermally transferred pattern for the protection against forgery, a special foil for thermal transfer and a manufacturing method of such a printing material. The method involves the following stages: arbitrary application of fibres on foil with an adhesive so that the foil for thermal transfer can be obtained; scanning and receiving the information characterising arbitrary distribution of the fibres; and storage of specific information in a data base of a computer-aided system of requests for the protection against forgery, which is connected to a telephone network and/or the Internet for public familiarisation and check of authenticity. By using the applicable methods and equipment for thermal transfer, the manufacturer of the printing material can manufacture the printing material with the protection against forgery, which has a local pattern, by means of thermal transfer with the thermal transfer foil. This invention makes a break-through in the area referring to the "pattern" in the existing state of the art and proposes one more new technical measure for the protection against forgery using fibres.

EFFECT: this invention saves enormous investments in special equipment, simplifies the production process, improves the production efficiency and reduces production costs.
