ABSTRACT:
A paper carrier substrate, has a contrasting layer applied thereto which thereafter is aluminized; in accordance with the invention, this contrasting layer is ordinary printing ink, which has a somewhat rough surface, permitting excellent adhesion of the metallized layer. In places where no ink is applied, the metallized layer will corrode off, thus leaving non-metallized markings. The ink is preferably applied by gravure or intaglio printing on the substrate, at a speed of between 5 to 9 m/sec., the printing roller being free from etchings where markings are to appear.
