Abstract

The present invention relates to a three-dimensional anti-counterfeiting code identifying paste and producing process, which relates to an anti-counterfeiting code identifying paste. In view of the defects that the existing anti-counterfeiting identifying paste is visual bar codes or geometrical patterns by directly seeing through eyes, and the effects of visually sampling, preventing producing and preventing counterfeiting are poor existing, the present invention provides the three-dimensional anti-counterfeiting code identifying paste and the producing process, of which the visual code and the cipher code are integrated, and the inner code and the outer code of the present invention are read by an infrared identifying reader. The present invention has the structure a base layer 1 which is provided with inner layer code in a printing mode is covered by a layer of covering film 2, and the covering film 2 is covered by outer layer code 3. The process of the present invention comprises selecting base layer material, printing the inner layer code, spraying the covering film, printing the outer layer code and cutting mould. The present invention has the advantage of good anti-counterfeiting effect, permanent identification and reading, long-term use under the condition of outdoor environment, etc.

Description

Stereo anti-fake sign indicating number mark label preparation technology

One, technical field

The present invention relates to anti-counterfeiting label, especially a kind of stereo anti-fake sign indicating number mark label preparation technology.

Two, background technology

At present, the security code mark label all is direct macroscopic individual layer plain code mark label, i.e. naked eyes visible bar code directly perceived or geometric scheme, and adopting recognizer also is directly directly to read from the figure sign indicating number.Existing the anti-person of making can be easy to be imitated from figure sign indicating number sampling intuitively, and antifalse effect is poor.At number of patent application 00116159.8, " false proof metallic barcode mark label of a kind of separable disposable use and preparation technology " patented technology is disclosed, said false proof metal sign indicating number mark label is exactly a kind of plain code mark label, still exists above-mentioned weak point.At publication number is CN1140501A, " a kind of multi-layer bar code arrangement that adopts wavelength separation " patented technology is disclosed, described secret piece is to adopt litho or aniline printing technology print to form, or employing electron beam or ion attachment techniques, electrofax or electrographic recording method, or the ink-jet technology printing forms, its printing process complexity, the high deficiency of cost.

Three, summary of the invention

The objective of the invention is to solve above-mentioned common anti-counterfeiting label weak point, and a kind of novel bright, private mark combination is provided, be covered with inner code and outer code on the overlay film two sides respectively, adopt the stereo anti-fake sign indicating number mark label preparation technology of infrared recognizer recognition.

Technical scheme that purpose of the present invention adopts is that its preparation technology may further comprise the steps:

A, select primer: non-cracking, no scar, clean, smooth primer;

B, printing inner code: use printing ink, offset printing or silk screen print inner code, air dry on round floor;

C, spray film: prepare overlay film printing ink by weight, prescription is for using phenolics oil 25-30g, light resinon 5-10g, alkyd resin oil 15-25g, varnish 5-15g, gel oil 2-8g, colloid calcium 5-10g, urge drier oil 2-3g, pigment 10-15g, putting into crucible together stirs, 90 ℃ of whipping temps, time is 20-40 minute, after stirring, put into the air gun that sprays paint, above the bottom that is printed on inner code, be placed with on the 420 order silk screens and spray, drying in oven with being sprayed with the bottom of overlay film, is put in thickness＜0.01 millimeter, bake out temperature is 80 ℃-100 ℃, and the time is 30 minutes;

D, printing outer code: will be covered with the bottom of overlay film, and adopt c, step preparation covering material prescription, the color of its pigment has contrast not, uses the serigraphy outer code, air dry;

E, cross cutting: last cross cutting is shaped.

The optional paper of primer of the present invention, perhaps PVC plastic sheet, perhaps sheet metal etc.

The present invention adopts phenolics oil, is to play cohesive action in film forming; The light resinon plays the gloss effect in film forming; Alkyd resin oil plays black cohesive effect in film forming; Regulator China ink oil plays the China ink corrective action; Gel oil plays the elasticity humidification; Colloid calcium plays thickening power; Urge drier oil to play and urge the effect of doing.

The present invention, above the layer at the bottom of being printed with inner code one deck overlay film is arranged, the overlay film that is covered can be penetrated recognition by the infrared light of wavelength 800 to 900 nanometers, be printed on outer code on the overlay film, can by wavelength the common ruddiness recognition of 600 to 650 nanometers, outer code equally also is to be that the infrared light of 800 to 900 nanometers penetrates recognition by wavelength, and the color of outer code and overlay film has contrast.

The present invention is when recognition, earlier by behind the common infrared light recognition of the recognizer outer code, give central processor CPU in the recognizer with the information transmission that reads, central processor CPU is opened the another one infrared light supply on the recognizer again, infrared light supply penetrates overlay film recognition inner code, give central processor CPU with the information transmission of being distinguished again, central processor CPU information internal by the relation of setting again, the input of outer code secondary carries out exporting to display device after the computing.

It is splendid that the present invention has antifalse effect, can distinguish for a long time, out of doors characteristics such as long-term use under the environmental baseline.

Four, description of drawings

Further specify the present invention below in conjunction with accompanying drawing.

Fig. 1 is an embodiment of the invention structural representation;

Fig. 2 is the present invention's effect synoptic diagram when distinguishing.

Among the figure: 1-bottom 2-overlay film 3-outer code

Five, embodiment

As shown in Figure 1, be covered with overlay film 2 on the bottom 1 of printing inner code, on overlay film 2, be printed with outer code 3.

Fig. 2 penetrates outer code 3 and outer code 3, overlay film 2 and is printed on the bottom of internal layer with the infrared light of ruddiness recognizer, distinguishes out the effect synoptic diagram of inside and outside sign indicating number.

Its preparation technology's of the present invention embodiment is as follows:

Select paper, use common ink, adopt silk-screen printing technique behind printing inner code on the paper, air dry, prepare overlay film printing ink by weight, with phenolics oil 30g, light resinon 10g, alkyd resin oil 20g, varnish 10g, gel oil 5g, colloid calcium 10g, urge drier oil 3g, red pigment 15g puts into crucible and stirs 90 ℃ of whipping temps, time is 30 minutes, put into the air gun that sprays paint then, above the bottom that is printed with inner code, be placed with on the 420 order silk screens and spray, thickness＜0.01 millimeter, the bottom of overlay film will be sprayed with, put into drying in oven, bake out temperature is 90 ℃, 30 minutes time, with phenolics oil 30g, light resinon 10g, alkyd resin oil 20g, varnish 10g, gel oil 5g, colloid calcium 10g, urge drier oil 3g, Chinese white 15g, put into crucible and stir, 90 ℃ of whipping temps, the time is 30 minutes, the printing ink of preparation, outer code is imprinted on the bottom that is covered with overlay film with serigraphy, air dry, last cross cutting is shaped.
