Description

Digital security line anti-counterfeiting self-adhesive paper

technical field

The utility model relates to a self-adhesive paper, in particular to an anti-counterfeit self-adhesive paper. the

Background technique

Security thread anti-counterfeiting paper is also called anti-counterfeiting paper with anti-fake thread. It is a kind of anti-counterfeiting paper that uses special devices or special techniques and means to embed a security thread (a thread made of metal or plastic or other special substances) into a specific position in the paper during the copying stage. Due to the inconsistency of the color of the security thread and the paper page and the particularity of the security thread, the anti-counterfeiting effect is achieved. Of course, there are also cases where security lines are applied to self-adhesive paper, but the information on the current security lines is just a simple text logo, which does not contain confidential information. It is realized by scraping ink, the production process is cumbersome, the cost is high, and with the continuous development of science and technology, some criminals can easily imitate the self-adhesive paper with the security line, so that the traditional security line self-adhesive paper The anti-counterfeiting strength has been greatly reduced. the

Utility model content

The purpose of the utility model is: a self-adhesive paper embedded with a unique fixed digital security thread or a random digital security thread (inquiry). The self-adhesive paper can achieve a higher anti-counterfeiting effect, so that it cannot be produced by non-papermaking methods. At the same time, the information on its digital security line can replace the traditional scratch-off ink, saving costs. the

The utility model is realized in the following ways: a digital security thread anti-counterfeit self-adhesive paper, which contains anti-counterfeit safety thread; the anti-counterfeit safety thread is embedded in the base paper layer of the paper in a window-opening type; Composed of three layers, the base paper layer is above the glue layer, and the bottom paper layer is below. The anti-counterfeiting security thread is a metal thread or a polyester plastic thread of different colors, a microprinting thread or a fluorescent thread, and the like. The width of the anti-counterfeiting security line is within 0.5mm-5mm, and the thickness is within 10μm-30μm. Anti-counterfeiting security threads include thermosensitive, magnetic, fluorescent, laser holographic, microtext, photolithography, and variable digital security threads. The minimum distance between safety lines is 15mm, and the minimum window size can reach 2mm for opening and 2mm for closing. The weight of anti-counterfeiting paper can reach 40-120g/m ² .

Compared with the prior art, the utility model has the positive effects that: the manufacturing process is simple and easy to implement; the utility model has strong versatility and can meet the needs of most customers; the production is flexible, and various process schemes can be selected according to the needs; and the structure is simple and easy to use , can be printed on the surface; the utility model can be mass-produced, reducing start-up costs and costs; flexible data, high anti-counterfeiting performance, and can replace the traditional scratch-off ink at the same time, reducing the production process and saving a lot of cost. the

Detailed ways

As shown in Figure 1, it is a schematic cross-sectional structure diagram of the present utility model. As can be seen from the figure, the anti-counterfeiting security thread 1 is embedded in the base paper layer 2 of the paper in a window-opening manner; The production steps of the digital security thread self-adhesive paper are as follows:

Make a fixed digital security thread 1: Arrange the data in a certain order, the data is composed of sequence numbers, and print (hollow out) onto the carrier of the security thread 1, in which the security thread 1 is 2 mm wide, 18 μm thick, and the data word height is 1.6 mm. Data upload to database for record. the

Layout design: design the required layout drawing for placing the safety thread; make the papermaking layout drawing, and set the line spacing according to the product size required by the customer. It is required that there must be at least one digital safety line 1 on each finished product, and the line spacing is 30mm. the

Plate-making and net-making: engraving the metal plate used in production, pressing the net, that is, using the metal template to press out the net mold required for white watermarking and window opening on the copper net, and spraying and sealing the convex part of the net mold with polymer resin; according to The papermaking layout diagram is used to make copper mesh, and then it is copied by a multi-network and multi-cylinder rotary paper machine, and the fixed digital safety line 1 is embedded at the same time. The window opening method is to open 5mm and bury 8mm. 80G digital security thread base paper layer 2. the

Welding mesh netting: make the watermarking net into a cage. the

Paper copying: The copying of this anti-counterfeiting paper is made by a multi-cylinder paper machine. It is a papermaking process combined with a variety of anti-counterfeiting technologies. More than two cages can be selected according to the use of the paper, and at the same time, the window can be opened and the line can be released. It is necessary to adjust the quantitative ratio of each composite layer paper at any time. Put the net cage into the net slot of the rotary paper machine for paper copying. During the copying process, open the window along the rotation direction of the net cage and release the safety thread continuously at the window opening position. The deviation of the safety line is within 2mm. Inside. the

Glue coating: uniformly coat hot melt adhesive or water sol on the back of base paper layer 2 to form glue coating layer 3; the

Molding: According to the customer's needs, the produced fixed digital security line 1 self-adhesive paper is cut into 597mm×889mm specifications, and the finished product is printed by an offset printing machine, and finally die-cut into 30mm×28mm specifications for customers to use. the

The safety thread 1 of the present utility model is divided into two kinds: fixed digital safety thread and random digital safety thread:

As the name implies, the fixed digital security thread is to print a fixed serial number or related product information on the security thread 1, while the random digital security thread is to print random numbers or related product information. Whether it is a fixed serial number or a random number, its information will be uploaded to the database for subsequent query and verification of authenticity. In the papermaking process, according to the different needs of different customers, the two kinds of security threads are embedded in the self-adhesive paper, and then the base paper layer 2 is produced through the papermaking process, and finally glued and combined to make this utility model. the

As shown in Fig. 2 and Fig. 3, it is a schematic diagram of the front and rear plane structures of the utility model. When the customer uses this utility model, the complete serial number and product information cannot be seen through the paper surface 5, only by scratching off the part of the digital security line 1 self-adhesive paper that closes the window (similar to the current scraping ink ), you can see the complete serial number and product information, and once the closed window part is scratched, it cannot be restored, thus playing the anti-counterfeiting function of the traditional scratch-off ink, and at the same time greatly reducing the production cost. the
