Abstract

FIELD: printing industry.

SUBSTANCE: multilayer protected composition is formed with an additional multilayer element. The element is formed on the paper surface. The element comprises a multi-colour coating in the form of periodic raster formed by at least two paints of different colours contrasting relative to the paper surface. The paints contain luminescent compounds having daily luminescence in the visible range of light under the influence of natural lighting. The combinations of paints are such that the integral colour of the additional multilayer protected element is visually perceived as unsaturated close to achromatic. One of the embodiments of the protected element forms graphic shape or is part of a graphic shape, which changes its visual display due to changing its colour grade and/or optical density and/or saturation when copying the document on a printing device operating in a colour system CMYK.

EFFECT: increased level of protection of paper or document from forgery by applying a new security feature.

Description

The claimed solution relates to the manufacture of compositions, in particular to the manufacture of multilayer composite products and protective combinations of layers with special properties that protect, in particular, paper from counterfeiting.

A composition protected from counterfeiting is used in the production of securities and documents requiring a high level of protection against counterfeiting, such as banknotes, passports, driver's licenses, etc.

Known technical solutions in the field of multilayer products using several layers of paint, phosphors, pigments, applied alternately on a paper layer in various versions, RU 2264296, RU 2199446.

Their disadvantage is that they are poorly designed to visually determine the authenticity of the protected paper and its products, such as banknotes and forms of securities, as well as excise and postage stamps.

The proposed technical solution is based on the use of multi-color solutions made by the printing method.

As already mentioned, technical solutions are known from the prior art for the production of multilayer compositions and the use of ink layers, the color of which lies outside the range of the color gamut of the CMYK color reproduction system to protect printing products from counterfeiting.

For example, decision RU 2199446 C2 describes a security pattern for securities, consisting of two or more adjacent areas having different color densities, and a region with a higher color density forms the subject. An overprint of geometric patterns is applied over these areas, the color and shape of which are selected so that upon visual observation the overall pattern looks homogeneous, and when photocopying the theme is clearly manifested.

RU 2264296 describes paper using two zones, one of which is made with pigment ink, and the second is ink containing daylight luminescence and having a color that lies outside the color gamut of four-color printing.

However, the indicated decision does not indicate the possibility of using a combination of chemical solutions, which, when visually observing the document, gives an integral color close to achromatic, creating the illusion that it lies in the color gamut of a conventional four-color printing.

In addition, a common drawback of methods for manufacturing multilayer compositions using layers and zones made with daylight luminescence inks without additional protective measures is that they use bright, eye-catching colors that are not always appropriate on papers, such as valuable documents like ID, bills or banknotes. As a result, on the one hand, the potential forger sees the presence of a bright color and will take steps to circumvent this problem (as it becomes “warned”), and on the other hand, it is impossible to seal any significant part of the ID with these elements banknotes due to the above disadvantage (very bright, "poisonous" colors).

Thus, the task of increasing the security of multilayer compositions in comparison with the proposed method is not fully solved, since this solution does not stipulate the possibility of using graphic elements made from raster of paints with day luminescence and giving an integral document during visual observation for protection against counterfeiting a color close to achromatic, creating the illusion that it lies in the color gamut of conventional four-color printing.

The objective and technical result of the proposed invention is the creation of a composition with layers, providing an increase in its level of protection against falsification due to the use of a new security feature.

The technical result is achieved in that the multilayer protected composition according to the first embodiment is made with an additional multilayer element formed on the surface of the paper, including a multicolor coating in the form of a periodic raster, made by at least two paints of different colors, contrasting relative to the surface of the paper, lying outside the area the color gamut of the CMYK system, and is characterized in that the paints contain luminescent compounds having daylight luminescence in the visible range of light However, under the influence of natural light, the combination of colors is such that the integral color of the additional multilayer protective element is visually perceived as unsaturated, close to achromatic.

According to the second variant, a multilayer protected composition with an additional multilayer element formed on the paper surface, including a multicolor coating in the form of a periodic raster, made by at least two inks of different colors, contrasting with the paper surface, lying outside the color gamut of the CMYK system, and characterized the fact that the paints contain luminescent compounds having daylight luminescence in the visible range of light under the influence of natural light, and an additional multilayer security element forms a graphic figure or is part of a graphic figure that changes its visual display by changing its color gamut and / or optical density and / or saturation when copying a document on a printing device operating in the CMYK color system.

Additionally, the technical result is ensured by the fact that under the multilayer protective element an additional carrier layer is made of paper and / or plastic and / or composite material,

a multicolor raster is made with inks with daytime luminescence and has additional color-changing properties, such that the graphic elements made with such a raster have an integral color close to achromatic, with the effect of being in the color gamut of a four-color print,

graphic elements are made on the basis of color moire, manifested when observing the composition from different angles,

multicolor raster is made by printing method,

a multilayer additional security element forms sections of the image, made in the form of geometric figures, guilloche elements, graphic and alphanumeric characters, forms an encoding or represents any combination of all of the above,

multicolor coating is formed by materials having different absorption in the infrared range of the optical spectrum,

additional multilayer security element contains an image representing information for identification and / or photograph for identification,

a transparent section is made under the multilayer protective element,

the multilayer security element is made with a latent image, visible in the light or when tilted.

The technical result is also achieved due to the fact that a multilayer secure composition, such as described in any version above, is made as a banknote, excise stamp, postage stamp, passport, travel document, driver’s license, identification card, security, security document, plastic card , label, packaging, payment document.

The essence of the claimed solution lies in the fact that the protective effect on such a composition is manifested in the fact that when a valuable document is observed, a slightly colored or achromatic element is visible, which, after copying on a color copier, changes its color gamut or saturation so that the visual perception of the document changes noticeably generally.

Such a multilayer composition is suitable for the manufacture of an article thereof in the form of a valuable document, which is a banknote, an excise or postage stamp, a passport, a travel document, a driver’s license, an identity card, a security paper, a plastic card, a label, a payment document or similar document protected from a fake.

Example 1

(According to paragraph 1 of the formula with signs according to dependent paragraphs 5 and 11).

A valuable document or paper in the form of a banknote contains a graphic element in the form of an alternating raster, made by offset printing method in three different colors: bright yellow, orange and bright blue (item 1 of figure 1), lying outside the color gamut of the CMYK color system.

In this case, bright yellow paint contains 3-methoxybenzantrone as a luminescent compound with daytime luminescence in the visible range of light under the influence of natural light, orange paint contains a mixture of 3-methoxybenzantrone with rhodamines C and 6G, and bright blue paint is arythylene substituted 2,5-diaryloxazoles.

Color combinations and color saturation and raster pitch are such that the integral color of the graphic security element is visually perceived as unsaturated, close to achromatic.

After copying a valuable document on the copier, the integrated color of the graphic element is distorted and changes the color scheme of the valuable document, which indicates its fake.

Thus, it is obvious that the technical result is achieved, according to the first embodiment of the invention, by applying a graphic security element containing a raster and executed with paints lying outside the color gamut of the CMYK system to protect a valuable document.

Example 2

(According to paragraph 2 of the formula, with signs according to dependent paragraphs 5, 6, 11)

The document or paper in the form of a label contains a graphic element in the form of different sections of an alternating raster with different steps, offset by the printing method in two different colors, bright yellow and bright blue (figure 2, 3), lying outside the color gamut of the CMYK color system .

In this case, the bright yellow paint contains 3-methoxybenzantrone as a luminescent compound having daylight luminescence in the visible light range under the influence of natural light, and the bright blue paint contains substituted arylethylene 2,5-diaryloxazoles.

Color combinations and color density and raster pitch of various sections of a graphic element are selected to form a given visual perception of the geometric shape and size of the graphic element. In figure 2, the stripes of the vertical sections of the raster should appear curved inward.

After copying a valuable document on a photocopier, the integral color of various sections of a graphic element is distorted and the visual perception of the geometric shape and size of its sections is violated, while the vertical lines in figure 2 will appear vertical, which indicates a fake document.

Thus, it is obvious that the technical result is achieved, according to the second embodiment of the invention, by applying for the protection of a valuable document a graphic security element containing various sections with different raster pitch and made with paints that lie outside the color gamut of the CMYK system.

Example 3

(Claim 1 with indications of dependent clauses 3, 9, 11)

The document in the form of a plastic card (item 2 of FIG. 4) contains a multilayer security element formed by a graphic element in the form of an alternating raster, made by offset printing method in two different colors, bright yellow and bright blue (item 3 of figure 4), lying outside the color gamut of the CMYK color system, at least partially applied on top of an additional layer in the form of a transparent section (item 4 in figure 4) on the surface of the map (“transparent window”).

In this case, the bright yellow paint contains 3-methoxybenzantrone as a luminescent compound having daylight luminescence in the visible light range under the influence of natural light, and the bright blue paint contains substituted arylethylene 2,5-diaryloxazoles.

The color combinations and the density of the colors and the raster pitch are such that the integral color of the graphic security element is visually perceived as unsaturated, close to achromatic.

After copying a plastic card onto the copier, the integrated color of the graphic element is distorted and changes the color gamut of the valuable document, and the degree of its change in the transparent window region and outside this region is different, which indicates its fake.

Thus, it is obvious that the technical result is achieved, according to the first embodiment of the invention, by applying a graphic security element containing a raster and made with paints lying outside the color gamut of the CMYK system and the dependent points 3 and 9 to protect a valuable document, by using an additional layer in the form of a transparent window.

Example 4

(Claim 1 with indications of dependent clauses 3, 4, 5, 6, 10, 11)

A valuable document or paper in the form of a banknote contains a graphic element in the form of an alternating raster, made by offset printing method in two different colors, bright yellow and bright blue (item 3 of figure 4), lying outside the color gamut of the CMYK color system.

A valuable document or paper contains an additional layer deposited on top of the graphic elements in the form of an embossed raster (figure 5), forming a hidden element in the form of a letter.

In this case, the bright yellow paint contains 3-methoxybenzantrone as a luminescent compound having daylight luminescence in the visible light range under the influence of natural light, and the bright blue paint contains substituted arylethylene 2,5-diaryloxazoles.

Color combinations and color saturation and raster pitch are such that the integral color of the graphic security element is visually perceived as unsaturated, close to achromatic.

When viewing a valuable document or paper at right angles, a hidden element formed by an additional layer is invisible. When tilting a valuable document or paper, a moire pattern appears in the form of a letter in the region of the additional layer (Fig.6).

After copying a valuable document or paper onto a copier, the integrated color of the graphic element is distorted, and changes the color scheme of the valuable document, which indicates its forgery.

Thus, it is obvious that the technical result is achieved, according to the first embodiment of the invention, by applying a graphic security element containing a raster and made with paints lying outside the color gamut of the CMYK system to protect a valuable document and the dependent items 3, 4, 5 and 6, by using an additional layer in the form of an embossed raster.

Example 5

(Claim 2, with indications of dependent clauses 5, 11)

The valuable document contains a multilayer security element formed by a graphic element in the form of an alternating raster with a variable pitch, offset by printing in two different colors, bright yellow and bright blue (Fig. 7), lying outside the color gamut of the CMYK color system.

In this case, the bright yellow paint contains 3-methoxybenzantrone as a luminescent compound with daylight luminescence in the visible light range under the influence of natural light, and the bright blue paint contains substituted arylethylene 2,5-diaryloxazoles.

The color combinations and the density of the colors are such that the integral color of the graphic security element is visually perceived as unsaturated, close to achromatic.

After copying a valuable document, for example, a plastic card on a photocopier, the integrated color of the graphic element is distorted and changes the color gamut, and the degree of its change within the raster with a varying step will be different, and forms two areas, the first - where the raster is saved, and the second - where the raster is converted to a solid background. Thus, the color gamut and the geometric shape of the graphic element will be distorted, which indicates a fake document.

Thus, it is obvious that the technical result is achieved, according to the first embodiment of the invention, by applying for the protection of a valuable document a graphic security element containing a raster with a variable pitch and made with paints lying outside the color gamut of the CMYK system.

Example 6

(Claim 1, with indications of dependent clauses 5, 8, 11)

A valuable document in the form of a plastic card (pos. 5 of Fig. 7) contains a multilayer security element formed by a graphic element in the form of an alternating raster, made by offset printing method in two different colors, bright yellow and bright blue (item 6 of Fig. 7) lying outside the color gamut of the CMYK color system.

In this case, the bright yellow paint contains 3-methoxybenzantrone as a luminescent compound with daylight luminescence in the visible light range under the influence of natural light, and the bright blue paint contains substituted arylethylene 2,5-diaryloxazoles.

The color combinations and the density of the colors are such that the integral color of the graphic security element is visually perceived as unsaturated, close to achromatic.

The security element contains information for identifying the person and a photo of the owner (item 7 of Fig. 7).

An additional layer is applied over the protective element in the form of an embossed three-dimensional raster, the strokes of which are turned at an angle of 5 ° relative to the printed raster.

When observing a document at a right angle, information is available for identifying a person against a colored background, similar in color to achromatic, and when viewing a document at a slope over the information for identification, colored moire stripes are observed (Fig. 8).

After copying a plastic card on a copier, the integrated color of the graphic element is distorted and changes the color scheme of a valuable document, which indicates a fake.

Colored moire stripes that appear when observing a document at an angle, are also absent on the copy, which indicates a fake.

Thus, it is obvious that the technical result is achieved, according to the first embodiment of the invention, by applying a graphic security element containing a raster and executed with paints lying outside the color gamut of the CMYK system to protect a valuable document and dependent points 5 and 8 by using identification information and photos of the owner.
