Abstract

A device for making security marks by means of a plurality of simultaneously backing and printing dies, each with a pre-designed image. The device makes it possible to subject a sheet of paper to a novelty simultaneous abrasion and printing method of a security mark using the dies previously and smoothly inked by means of inking rollers with either one or more inks not visible to the naked eye, but revealable by one or more temporarily applicable revealing stimuli, wherein the security mark shows as authentication evidence a pre-designed image invisible to the naked eye, but which becomes visible in many different ways, and at least one second form of verification under a revealing stimulus, wherein all forms in which the images are revealed on the paper have an absolute matching location because they are produced simultaneously and by the same backing and printing die.

Dependent claims

A device for making security marks positionable on a sheet of paper comprising a main rotary cylinder for backing said sheet of paper, wherein said supporting main rotary cylinder includes retaining means of said sheet of paper, and a rotary grinding wheel adjacent to the perimeter of said supporting main rotary cylinder with a distance of approach adjustable regarding said supporting main rotary cylinder, wherein said device is characterized by further comprising:

at least one simultaneously backing and printing die comprising a free face with a pre-designed image, which is mounted on said perimeter of said main rotary cylinder, wherein said at least one simultaneously backing and printing die is suitable for backing said sheet of paper against said grinding wheel at the distance of approach sufficient to wear out the front of said paper without passing through it and matching said pre-designed image, and is suitable for printing simultaneously said pre-designed image with ink on the reverse of said sheet of paper, and
at least one first inking roller train comprising at least one first applicator roller of said ink and that is positioned so as to make contact with said free face with said pre-designed image of the simultaneously backing and printing die.

A method for making security marks positionable on a sheet of paper on a device comprising a main rotary cylinder for backing said sheet of paper, wherein said supporting main rotary cylinder includes retaining means of said sheet of paper, and a rotary grinding wheel adjacent to the perimeter of said supporting main rotary cylinder with a distance of approach adjustable regarding said supporting main rotary cylinder, wherein said method is characterized in that comprises the following steps:

a) mounting on the perimeter of said main rotary cylinder for supporting at least one simultaneously backing and printing die comprising a free face with the pre-designed image,
b) inking said free face with the pre-designed image of said at least one simultaneously backing and printing die by means of at least a first applicator roller of ink of a first inking roller train,
c) moving the sheet of paper to the main rotary cylinder, retaining said sheet of paper resting on said at least one simultaneously backing and printing die with its face already inked, wherein the sheet of paper is retained by said retention means, and
d) grinding said sheet of paper with a rotary grinding wheel so that the distance of approach causes wearing out of the front of said paper without passing through it and matching said pre-designed image, and simultaneously printing said pre-designed image with said ink on the reverse of said sheet of paper.
