Problems solved by technology

This invention is extremely difficult to counterfeit and easy to identify, but its production is difficult, with high scrap rate and low efficiency, especially to prevent the front and back printing surfaces from being reversed due to the flipping of the digital security line, the speed of the paper machine cannot be driven fast, and it is not suitable for high-speed production

Embodiment 1

[0023] Such as figure 1 As shown, printing and dyeing a chromatographic line (or printing a film, and then cutting into very narrow thin lines as chromatographic lines).

[0024] Select a 20-count white polyester yarn, and use a segment dyeing machine to print and dye some color segments (2) with each color segment length of 3mm on it, choose black (A), red (B), yellow (C), green (D), blue (E) color segment (2), according to the arrangement order of black (A), red (B), yellow (C), green (D), blue (E), each interval is 10mm It is printed and dyed on polyester yarn to form a chromatographic thread (1). Since the color segments (2) of the above five colors are arranged in groups according to a fixed order, the color sequence characteristics of each group must be the same. If 5 color segment lengths are used as a set of anti-counterfeiting information, and they are arranged and combined in different orders, the above five colors can have 3125 permutations and combinations. In ot...

Embodiment 2

[0026] Such as figure 2 , Figure 4 As shown, a chromatographic line anti-counterfeit paper and its chromatographic line anti-counterfeit medicine box are manufactured.

[0027] The first step is to spread the chromatographic lines (1) made in the above example in parallel and evenly in the paper at a distance of 30 mm; increase the transparency of the surface paper layer as much as possible so that the color segments (2) can see through It can be directly seen by the naked eye through the paper surface; according to 230g / m 2 The standard copying out chromatographic line anti-counterfeiting paper (3) is standby (referring to figure 2 ).

[0028] In the second step, adopt the above-mentioned chromatographic line anti-counterfeiting paper (3) to print out the chromatographic line anti-counterfeiting medicine boxes of 105mm * 150mm one by one (see Figure 4 ). And the anti-counterfeiting feature (color sequence feature) statement: "This medicine box is printed on the speci...

Embodiment 3

[0030] Such as Figure 5 As shown, a 20-micron transparent film is selected, and some color segments (2) with each color segment length of 2 mm are printed on it, and black (A), red (B), yellow (C), green (D) are selected. ), blue (E) five color segments (2), in the order of 'black, red, yellow, green and blue', print them on the transparent film at intervals of 3 mm, and then cut them into 0.4 mm wide and 10 mm long Thin lines whose color sequence is characterized by 'black, red, yellow, green and blue (ABCDE)' constitute a special chromatographic line (1).

[0031] The prepared chromatographic lines (1) are added into the pulp during papermaking and stirred evenly, so that the anti-counterfeit paper with randomly distributed chromatographic lines can be produced. Only providing the anti-counterfeiting paper with the same color sequence feature to the same user can play a very good anti-counterfeiting effect.

[0032] Using the chromatographic line anti-counterfeit paper (3...

Abstract

The invention provides a chromatoghraph line antiforge method and antiforge paper. Fine lines are buried in the paper and the colour permutatuin combination character of fine line is called as colour order character and as antiforge character. The antiforge paper of the same colour order character is only used for the same users or the same brand or other the same antiforge object. The chromatoghraph line antiforge paper is suitable for high-speed production and is hard to forge and easy to identifying.

Description

Technical field: [0001] The invention relates to an anti-counterfeit method and anti-counterfeit paper, in particular to an anti-counterfeit method and anti-counterfeit paper which use the color sequence characteristics of thin lines (safety lines) as identification basis. technical background: [0002] Chinese patent application No. 03106251.2 provides a patent titled "Structure-corresponding digital anti-counterfeit printed matter and its manufacturing and identification method". It embeds a digital security line inside the paper of the anti-counterfeit printed matter. When checking the authenticity, you can use telephone, Communication tools such as the Internet, short messages, and networked scanning readers input some numbers on the digital security line into the computer anti-counterfeiting identification system, and compare and verify them with the numbers archived in the database to identify the authenticity. There are two or more digital security lines embedded in t...
