LT4319B - A method for making of identifiables symbols - Google Patents

Abstract

Invention applies to the production methods of special graphic images intended for the protection against falsification. The patented production method of the identification marks, when the identification marks are graphic images, created by computer software and afterwards, selecting colours of visible and invisible inks, are printed by an ink jet printer. Besides, depending on the desired level of protection against falsification, all graphic images are printed by invisible inks of various colours, or a part of it is printed in visible inks and the rest printed in invisible inks of various colours, or all the graphic images are printed in visible inks of various colours, afterwards laying the same image on the visible one, but using invisible inks, and so on, and so forth.

Description

The invention relates to methods for producing special graphic characters. These marks, as special markings, can be used to protect documents from tampering, to protect cars from unauthorized use, and elsewhere.

There is a known method of producing identification marks-holographic marks {RU, no. 2035315, B 44F 1/12, 1995) having sophisticated manufacturing technology.

Known multilayer material with diffractive structures (LT, no. 327, B 23 B 23/12, B 23 B 7/02, 1994), from which signs are cut and glued onto documents. Because the diffractive structures formed in this material are only identified in the narrow visible part of the light spectrum, the marks do not provide sufficient protection against forgery of documents and the complexity of their production technology.

The closest thing to patenting is the production of identification marks. Method (LT, No. 3907, B 60 R 25/00, 1995), wherein the marks in the form of graphic images are made with a single color invisible ink, highlighted by ultraviolet light. In the patent cited, these marks are used to protect vehicles from unauthorized use by designating individual automotive parts, assemblies.

These signs also do not provide sufficient protection against counterfeiting as they are not complex.

The object of the invention is to increase the reliability of identification marks by using a full color spectrum of visible and invisible inks and computer technology.

This problem is solved by the method of producing identification marks, where the identification marks are graphic images made with a single color invisible ink, highlighted by ultraviolet rays, in that the graphic images are created by a computer program and then selected for each of them by the colors visible. and invisible inks and prints with an inkjet printer.

In addition, depending on the degree of protection against counterfeiting sought, the entire graphic shall be printed in various colors with invisible inks and the remainder shall be printed in invisible various colors or the entire graphic shall be printed with visible various colors and then repeated on the same. invisible ink and the like.

The advantage of the patented method of producing identification marks is that it produces a complex color image by using visible and invisible inks of various colors and computer technology, in particular when ultraviolet light is used because invisible inks are luminescent. In addition, this method provides a great variety of brands and enables the automation of the production process.

According to the invention, the method of producing identification marks comprises the following operations: a signature program to create a graphic representation of the mark, execute it on a computer, then select the colors for visible and invisible ink and print it on an inkjet printer.

The ability to create a reliable brand in a proprietary way is determined by the graphic imaging software, the level of graphic design of the mark, the color of the ink in the ultraviolet light and the type of printer.

-3EN 4319 B

The identification marks can be realized directly on the protected document, on paper or film, followed by cutting and pasting the marks on the protected object, as well as on a polymeric film carrier for laminating the protected document.

Because invisible inks are luminescent, the true image of the mark is visible under ultraviolet light.

Compliance with the identification mark on a protected object shall be verified by means of a technology card describing the distinguishing features of the mark by exposure to ultraviolet light of the appropriate wavelength. The technology verification cards shall be drawn up for each mark and handed over to the document holder and inspection bodies.

Claims (4)

DEFINITION OF INVENTION 1. A method of producing identification marks, wherein the identification marks are graphic images produced by invisible ultraviolet rays in invisible ink, characterized in that the graphic images are generated by a computer program and then selected for each graphic image in visible and invisible inks and printed with an inkjet printer. 2. The method of claim 1, wherein the entire graphic is printed with invisible ink of various colors. 3. A method according to claim 1, characterized in that a portion of the graphic image is printed in visible and the rest is invisible in various colors. 4. The method of claim 1, wherein the entire graphic is printed with visible inks of various colors and then reproduces the same image with invisible inks.
