Problems solved by technology

However, these two methods are currently unable to fight anti-counterfeit products on the market, which is very distressing, because as long as you buy the same ink, and this ink is more common in the market, or laser engraving is also used, the cost is not much higher than ordinary engraving. This can achieve the same effect, so there is no way to carry out better anti-counterfeiting. The equipment used is the ordinary inner printing or outer printing of the printing factory. This printing method is easier for manufacturers with printing machines to counterfeit.

Embodiment

[0015] As shown in Figure 1, it is a schematic diagram of the structure of the palm-joining machine. The palm-joining machine is composed of an unwinding place 1, an EPC deviation correction device 2, an inkjet printer 3, a connecting bracket 4, a photoelectric sensor 5, a fan 6, a film guide roller 7, Rewinding traction main drive roller 8, synchronous encoder 9, main frame wallboard 10, the main engine tail wallboard 11 that has main drive motor inside and unwinding place 12 are formed.

[0016] A digital anti-counterfeiting label inkjet method is:

[0017] The first step. Modify the palm machine

[0018] On the side of the host wallboard 10 at the upper end of the EPC correction device 2, the inkjet printer 3 with a PC is installed through the connecting bracket 4, and the photoelectric printer 3 is installed on the upper end of the host wallboard 10 close to the inkjet printer 3 with the PC through the bracket. Inductor 5, a synchronous encoder 9 is installed on the windi...

Abstract

The present invention relates to anti-fake digital label printing method, and features that the gluing machine is refitted, so that when the printed label passes through the PC controlled code spraying machine, the photoelectric inductor receiving the label signal sends corresponding signal to the PC controlling the code spraying machine and the PC controls the code spraying machine to spray anti-fake digit to each label. The present invention has the advantages including capacity of spraying code in gluing machine and hard deciphering of the sprayed digital code.

Description

technical field [0001] The invention relates to a printing method of a digital anti-counterfeit label, which can be used on the outer packaging labels of beverages, food and daily chemical products to prevent counterfeiting of products, and belongs to the technical field of printing methods. Background technique [0002] The current product anti-counterfeiting generally uses the method of printing ink to change color under ultraviolet light or uses laser engraving during printing plate making to make the pattern and text finer and clearer, which is used to distinguish products printed by other plate making methods. But these two methods are currently unable to fight against anti-counterfeit products on the market. It is very distressing, because as long as you buy the same ink, and this ink is more common in the market, or laser engraving is also used, the cost is not much higher than ordinary engraving. This can achieve the same effect, so there is no way to carry out bette...
