| 摘要 |
<p>The invention concerns a film (7a) produced by printing on a top sheet (1) with non-glossy surface (2), a first glossy varnish imprint (3) adhering on said surface (2). A second continuous imprint produced on the first, adheres neither on the top sheet (1) nor on the varnish (3), and the film (7a) is completed. A glossy imprint (9) is thus provided in the film (7a) external surface (8) which is then applied on a document (12) to protect it from being reproduced by optical scanning.</p> |
