Реферат: In producing a film by printing on a top sheet with non-glossy surface, a first glossy varnish imprint adheres on the surface. A second continuous imprint produced on the first, adheres neither on the top sheet nor on the varnish, and the film is completed. A glossy imprint is thus provided in the film external surface which is then applied on a document to protect it from being reproduced by optical scanning.
