Abstract
The present disclosure discloses a specific bar code and a forming method of the bar code, comprising: forming without a particular order on the printing stock: at least a one-dimensional bar code and color information and/or grayscale information in an area corresponding to the one-dimensional bar code, which are superimposed on the printing stock, respectively, wherein data information is generated by identifying the color information and the grayscale information; and if acquired by a portable electronic device having an image capture function, identifying the one-dimensional bar code and the color information and/or grayscale information, respectively, wherein a false positive ratio of identifying the one-dimensional bar code is less than 40%. By superimposing colorful background on the one-dimensional bar code, the present disclosure expands the coding capacity and implements one-code-for-one-article identification so as to bring additional values to vendors for applications such as traceability of one code for one article, while maintaining the features of one-dimensional bar code.
