Embodiment Construction

[0016] like figure 1 As shown, in the working process of a method for making and identifying an ultraviolet barcode of the present invention, the barcode is printed with ultraviolet ink and pasted on the carrier. The ultraviolet light source emits ultraviolet light to the surface of the barcode, which excites the ultraviolet ink to emit visible light to the barcode reading machine. After the barcode reading machine receives the light, it filters the ultraviolet light through the polarized light interception technology, and enters the available light into the sensor of the barcode reading machine. Perform imaging decoding and read out barcode information.

[0017] The barcode printed with ultraviolet ink is invisible (invisible to the naked eye), anti-counterfeiting, and wear-resistant; and it can realize normal reading of the barcode under the ultraviolet environment and by an ordinary barcode reader. It can be used in special industry applications such as anti-counterfeiting...

Abstract

The invention relates to a method for manufacturing and identifying ultraviolet bar codes. The method comprises the following steps: forming a bar code pattern of bar codes containing information in a printing system by a digital ink-jet printing technology; uniformly spraying ultraviolet printing ink on a medium surface according to the bar code pattern by a digital printing system; emitting ultraviolet light to the medium surface by an ultraviolet light source and exciting the ultraviolet printing ink to emit visible light; receiving the visible light by a bar code recognizer, filtering the ultraviolet light by a polarized light intercepting technology to enable the visible light to enter a sensor of the bar code recognizer; and decoding the bar code pattern by a decoder in the bar code recognizer to restore and identify the information form the bar code. Compared with the prior art, the invention has the advantages that the novel anti-counterfeiting method improves the safety assurance capability of social data, is combined with two-dimensional bar codes to add the anti-counterfeiting data capability unrecognizable for naked eyes, adopts the anti-counterfeiting technology with low cost and is easy to widely use.

Description

technical field [0001] The invention relates to a barcode identification technology, in particular to a method for making and identifying an ultraviolet barcode. Background technique [0002] At present, the existing universal barcode reading technology adopts infrared scanning; since infrared is not in the range of visible light, its application is limited to specific environments. The light reflected by the object irradiated by ultraviolet rays is still in the visible light range, so this method has more general application and promotion value. Contents of the invention [0003] The object of the present invention is to provide a method for making and identifying an anti-counterfeiting ultraviolet barcode in order to overcome the above-mentioned defects in the prior art. [0004] The object of the present invention can be achieved through the following technical solutions: a kind of making and identification method of ultraviolet barcode, it is characterized in that, th...
