Abstract

FIELD: physics; marking.

SUBSTANCE: invention relates to protected printing products, specifically to excise stamps meant for controlling production, turnover and sale of alcoholic beverages. The excise stamp comprises a base paper with a non-printable region for variable information. In the base paper there is a protective metal-coated thread with an irregular visual image in form of a longitudinal continuous window with varying width. The thread has a graphic image which is invisible under ordinary illumination but visible under UV radiation, a latent image in form of a strip which is visible through a polarisation filter. The thread is partially put into the paper. Coloured strips with visible continuation in places where the thread is completely inside the paper are made on the thread at an angle. On the base paper there is a copper-coated foil with a holographic complex image with a non-metal coated picture with wide and narrow elements. On the base paper there are protective elements made from optically variable ink which changes colour characteristics when the viewing angle changes, device control elements, elements made from transparent lacquer which are visible in reflected light under effect of UV radiation, graphical protective elements, elements with luminescence under UV radiation and elements with metameric properties on infrared absorption.

EFFECT: invention increases security and simplifies authentication of federal special marks.

Description

The invention relates to secure printing products, in particular excise stamps, designed to control the production, turnover and sale of alcoholic beverages.

A technical solution is known - a federal special mark for marking alcoholic beverages produced in the Russian Federation, enforced by a decree of the Government of the Russian Federation dated December 21, 2005 No. 785 (see “Description of federal special marks for marking alcoholic beverages manufactured in the Russian Federation” ”, FSUE“ Goznak ”, 2006, p.5-8). The well-known federal special stamp is made on special self-adhesive paper and has the following security features:

unprintable area for applying variable information;

a security thread completely inserted into the base paper with text having luminescence under the influence of UV radiation;

protective fibers introduced into the base paper, including step fibers, having sections of different sections with different optical properties;

pressed foil with aluminum metallization with repeating holographic image and demetallized ornamental pattern;

chemical protection introduced into the bulk of the base paper, which is visualized (the paper is painted in a specific color) when exposed to a special reagent;

a repeating pattern printed on the back of the base paper, part of which is invisible under normal lighting and has luminescence under the influence of UV radiation;

a protective element made by a screen method of optically variable ink;

the words "RUSSIA", visible in oblique light, flexographic printed with a transparent ink, luminescent under the influence of UV radiation;

element printed with offset ink with special properties controlled by the device;

elements with luminescence under the influence of UV radiation;

the use of infrared absorption metameric paints when printing text: two inks that have the same black color, while one of the inks has visible and the other has invisible properties under the influence of infrared radiation;

arcuate notches preventing re-sticking of the brand;

protective graphic elements.

The disadvantages of the known technical solutions include the following. The full introduction of the thread into the paper allows it to be simulated by overprinting or gluing between two layers of paper. Holographic foil with aluminum metallization is widespread and can be imitated quite accurately. Optically variable paint has only visual properties and can be imitated by other available and widespread paints and varnishes.

There is also a method of identifying excise stamps and other securities using a protective magnetic thread (WO 9635586 A1, 1998). A soft magnetic material is applied to the plastic substrate. This magnetic material generates a signal or a series of signals in the polling strip created by the detection system to determine the reading or identification of products from a distance. The disadvantage is the high cost of the products themselves, systems for identifying these products, as well as the ability to simulate magnetic metallized yarn in fake products.

A well-known excise stamp (RU 39965 U1, 2004.08.20, G09F 3/00) containing two glued substrates, between which is placed a label with an information code. The tag is made in the form of a RFID tag with a once programmable read-only memory device. Such a label is difficult to control.

The problem solved by the invention is to increase security and facilitate authentication of federal special brands. As a result of the implementation of the invention, the economic damage caused by the production and distribution of counterfeit alcohol products with fake brands will be reduced.

To solve this problem, an excise stamp is proposed, which includes base paper with an unprintable area for applying variable information, a protective metallized thread is introduced into the base paper with an irregular visual image in the form of a longitudinal continuous window of variable width, and the thread is partially inserted into the paper, onto the thread under colored stripes are applied at an angle, having a visible continuation in places where the thread is completely in the paper, a foil with metallization of copper, holographic complicated, is applied to the base paper image with a demetallized pattern containing wide and narrow elements, protective elements made of optically changing ink are applied to the base paper, which changes color characteristics when changing the angle of view, elements for instrument control, elements made of transparent varnish, visible in reflected light and under exposure to UV radiation, graphic protective elements, elements having luminescence under the influence of UV radiation, and elements having metameric IR absorption properties.

The window width in relation to the width of the thread is mainly 25-75%. The thread contains an image invisible under normal lighting, for example, in the form of direct and inverted abbreviations "RF", visualized under the influence of UV radiation, a latent image in the form of stripes, visualized through a polarizing filter. Elements for instrument control can be made, in particular, in the form of geometric elements - semicircles.

The drawing shows an embodiment of the declared excise stamp (top view).

The excise stamp contains base paper and has an unprintable region 1 for applying variable information. A security thread 2 is introduced into the paper, on which an irregular visual image is formed in the form of a longitudinal continuous window 3 of variable width in the paper. The thread is metallized, has 4 colored stripes deposited on the thread at an angle, a latent image, text visible under the influence of UV radiation, in the form of direct and inverted abbreviations "RF". Colored stripes 4 have a visible continuation in places 5, where the thread is completely in the paper, which will not allow to simulate the thread by pressing the foil. The latent image in the form of stripes is visualized through a polarizing filter.

The excise stamp contains foil 6 with metallization with copper, a holographic complicated image, demetallized pattern 7, containing wide and narrow elements that cannot be reproduced using blind embossing. To protect the optically variable paint from imitations, the brand used paint, including public (visual) and cash authenticity levels 8. The paint has a change in color characteristics with a change in the angle of view, polarization properties visualized through a polarizing filter, a luminescent kinetic effect with a change in color over time.

When checking the authenticity of an excise stamp, a latent image on a thread in the form of stripes is visualized through a polarizing filter. Colored stripes do not allow imitation of thread by pressing foil. A demetallized foil pattern containing wide and narrow elements cannot be reproduced using blind embossing. Copper-coated foil has a limited distribution, is difficult to manufacture, which will lead to a significant reduction in the number of counterfeit brands.
