Problems solved by technology

[0003] However, since the watermark is formed in the paper by using special technology to form the required logo and pattern in the paper, the color of the fiber at the watermark is the same as that of the paper fiber, and more anti-counterfeiting elements cannot be added to the watermark, so it cannot be realized. The production of color watermarks and functional watermarks has poor visual effects

Embodiment 1

[0030] This embodiment provides a machine-readable anti-counterfeit paper containing color artistic watermark effect, which is prepared through the following steps:

[0031] (1) Use cotton fiber as raw material, add chemical additives to the paper, and process it into paper with a quantitative weight of 40-70g / m2. During the papermaking process, add dyes with fluorescent effects to the pulp to make a green color paper (such as figure 1 ), and then process the colored paper into a green leaf-shaped paper sheet with an area of ​​0.5-5cm2 by pressing or cutting (such as figure 2 );

[0032] (2) In the papermaking process, use the positioning release device 2 to place the anti-counterfeit paper with the above-mentioned green leaf-shaped paper sheets on one side of the wet paper sheet 3 formed by the rotary screen cage 1 of the paper machine by using the positioning release device 2. Strip, compounded with another layer of wet paper 3, as the papermaking progresses, the above-me...

Embodiment 2

[0036] This embodiment provides a machine-readable anti-counterfeit paper containing color artistic watermark effect, which is prepared through the following steps:

[0037] (1) With reference to step (1) of Example 1, blue or red colored paper is obtained by copying, and processed into paper strips with a width of 1-10 cm and a length of 5-50 cm, and are cut or cut in the middle of the paper strip Process a hollow heart shape to obtain an artistic graphic paper sheet with a hollow area, the cross section of which is as Figure 4 shown;

[0038](2) In the process of paper copying, referring to step (2) of Example 1, the above-mentioned art graphic paper sheet with a hollow area is compounded between two layers of paper to complete the copying process and obtain a machine with a color artistic watermark effect. Read security paper.

[0039] When the anti-counterfeiting paper is observed against the light, an obvious blue or red colored paper tape can be observed. Similar vis...

Embodiment 3

[0041] This embodiment provides a machine-readable anti-counterfeit paper containing color artistic watermark effect, which is prepared through the following steps:

[0042] (1) Use cotton fiber as raw material, add chemical additives to the paper, and process it into paper with a quantitative weight of 40-70g / m2. During the papermaking process, add red temperature-changing fibers, blue fluorescent fibers and magnetic fibers to the pulp. fiber, paper that contains the above-mentioned anti-counterfeiting elements is obtained, and then the paper is processed into paper sheets with animal graphics or flower graphics with an area of ​​0.5-5mm2 by means of pressing or cutting;

[0043] (2) During the papermaking process, refer to step (2) of Example 1, compound the above-mentioned paper sheets with animal graphics or flower graphics into the middle of two layers of paper to obtain machine-readable anti-counterfeiting paper with color artistic watermark effect .

Abstract

The invention relates to machine-readable anti-counterfeit paper with color artistic watermarking effects and a manufacturing method thereof. The anti-counterfeit paper provided by the invention has a sandwich structure formed by two pieces of paper and a piece of artistic pattern paper disposed between the two pieces of the paper. The invention also provides the manufacturing method of the machine-readable anti-counterfeit paper with the color artistic watermarking effects. The anti-counterfeit paper provided by the invention is an innovation on the basis of present anti-counterfeit watermarking paper. On the basis of the present paper watermarking anti-counterfeit, the anti-counterfeit paper provided by the invention adds a plurality of anti-counterfeit elements to the paper watermarking part, thus achieving an effect of different transparencies of watermarking patterns. In addition, by utilizing paper composite technology, the anti-counterfeit paper provided by the invention achieves manufacture of color watermarks and functional watermarks, attaches color and different anti-counterfeit requirements to the watermarks, and improves the anti-counterfeit level of the paper.

Description

technical field [0001] The invention relates to an anti-counterfeiting paper and a manufacturing method thereof, in particular to a machine-readable anti-counterfeiting paper containing color artistic watermark effects and a manufacturing method thereof, belonging to the technical field of anti-counterfeiting paper product preparation. Background technique [0002] Paper anti-counterfeiting is an important aspect in the field of anti-counterfeiting. The existing paper anti-counterfeiting technology is mainly to prevent counterfeiting by setting watermarks, security threads, special fibers, etc. in the paper. Existing paper watermarks are mainly formed by accumulating different amounts of fibers in different regions during the copying process with watermark rollers that have been embossed with watermark patterns in advance. According to the transparency of the watermark, it can be divided into black watermark and white watermark. Black watermark is to form a watermark patte...
